View Full Version : Why are computer fonts still Imperial-based?

Why do we still use inches to define our font sizes?

Computer stuff is supposed to be bleeding-edge wave of the future, etc, but font size X is still defined as exactly X/72 inches (http://www.unitarium.com/font).

in fine Imperial system tradition, 72 is of course a completely ridiculous number to use.

is there any move to redefine this?

I would have thought that in the imperial system, 72, i.e. 6 dozen, makes good sense sense. It's half of 144, a number also known as "one gross", thus making 72 only half gross. :D

But seriously: some habits are hard to discard. Where I live we've been using metric measurements for over 30 years, but I still sometimes think of body weight and height in terms of the imperial units.

Mainly because it mirrors the printing world, and typefaces are imperial in the printed world because they date back to the printing press

We use logical numbering for fonts once we get off this Babylonian, base-twelve nonsense for time and angle/degree measurements.

(Seriously though, I want decimal time.)

Well, the base for all computers is binary and not decimal... and that isn't going to change any time soon (if ever) ;)

When Oz changed from imperial to metric due to the world agreement that it was a part of, one of the things that we have never been able to become fully metric on is plumbing fittings.

For obvious reasons.

Whats wrong with time as it stands most people can cope with lots of base systems . If it was good enough for the Babylonians then it's good enough for me, By the way the Babylonians main system was Sexagesimal which time is based on. 60secs = 1min 60min = 1hour

I'd actually like to see the West change its calendar to be inline with the phases of the moon. The days & months would then at least mean something more than just making the year be mathematically correct (as best it can).

I think that the reason we still have 12-based (or 60-based aswell) time measurement is simple: so days/hours/minutes can be divided for 2, for 3 and for 4 without generating something weird..

Think about it, would it be better saying "we'll meet at 12:20 PM" or "we'll meet at 12,33333333333333333333333333333333333 PM"?

The French did decide to do decimal times and dates right about the time they were lopping aristo's heads off http://en.wikipedia.org/wiki/French_Republican_Calendar - somehow it didn't catch on.

More to the point, why are we using this inefficient decimal Kilo/grams system when we could be using machine friendly Hexadecimal pounds/ounces/drams ( 1lb = 16 oz = 256 drams)

As a professional scientist, I've been using the MKS system for over 50 years - and I still think in (and prefer) miles/stones/acres etc!

Agreed somehow it is easier to imagine old imperial measures rather than Metric ones. even though i have used the metric system for most of my life.

This is probably a FUD, but it can make a good joke.

Why are the thrusters of the space shuttle as wide as they are?

They could only be transported by trains on rails, so the thrusters had to fit on the rails. The train rails are as wide as they are, because of an old Imperial standard, which was based upon the old Roman roads. The Romans build their roads as wide as they did to match the number of horses that were pulling their wagons/chariots. The width of the thrusters of the space shuttle are based on the "two horse butts" metric used in ancient Rome.

Because fonts were developed in Europe at a time a few hundred years before the invention and adoption of the Metric System, and because computers and computer technology is a historically American phenomenon. While I certainly "get" the utility of the Metric System, I've never needed to use it, so I really can't say if the whole "fonts are Imperial System-based" is good, bad, or indifferent.

I suspect it's indifferent, but that's just my opinion.

except that you wouldn't say 12,333...3 any more than you now pick odd times like 13 minutes and 45 seconds past 12. You pick the nearest sensible time point. 12,3 or so. Also, the meaningful fractions of an hour might change if you have, say, 10 hrs in a day, in stead of 24.

The link goes: Rome -> England -> USA -> Space Shuttle. As Cuddles McKitten points out this is not entirely true. However, it is true that often times people stick to old ways and standards pass the time that they should be changed.

leap months every 2nd or 3rd year, and "some calendars rely on direct observations of the state of vegetation" to determine when to insert them.

Well , maybe that in itself isn't terribly hard, but I imagine calculations that involve time spans would quickly become rather impractical.

Also, dates would always be "give or take 2 weeks". For (at least some) yearly recurring events, that might be ... inconvenient.

No. He said that since Americans use the Imperial system, the reason for the size of the space shuttles' thrusters are a result of the Romans coming up with the system in the first place, and he said it in a humorous way.

wouldn't the 5-6 extra days lumped in at the end get the next lunar month out of sync with the monn cycle, by 5-6 days or something ?

Yup! I'm old and senile but can still convert between virtually any units system in my head!

Imperial (and their continental counterparts) units were all based on some historically "visual" unit- that everyone could understand ( I know what a metre is - ~3'3" but visualizing 1/10,000,000 of the distance between the equator and the N. Pole is conceptually more difficult)


The argument that decimal units make it easy to calculate has never held water with me either - in practice I've found larger/more frequent mistakes made by tyro's who can't seem to get the Decimal point in the right place - something that happens less frequently when you're not using decimal!.

Traditionally the point wasn't exactly 1/72 of an inch. However Adobe rounded their definition of the size of a point to that size for PostScript - presumably to make calculations easier. No doubt if they had been in a metric-using country they would have rounded to the Metric system. See here. (http://en.wikipedia.org/wiki/Point_(typography)#Traditional_American_point_syst em)

The calendar we use today is descended from a partly lunar one. The original Roman calendar had ten months, but through reform two more were added (this is why September-December do not line up with the numbers their names imply). To keep it aligned with the solar year, the government would decide each year whether to add days. This caused confusion because the days were usually added to lengthen the terms of political allies or boost popularity through holidays rather than following any pattern. Julius Caesar moved to a purely solar calendar with influence from Egypt, setting the year length at 365 with a leap day every four years. With a slight modification in the 1500s to skip the occasional leap day, this is the calendar we use today.

I'm not senile (not that I know, at least), and I hate conversions.
I can visualize, say, a rectangular volume of 2 cubic meters, but I've had to negociate freights with people who measured volume in cubic foot.

So, tell me, this 1x1x2 meter trunk of mine, what's its volume in cubic feet ?


Most traditional units will be derived from some reference people easily get (parts of the body, the length of a stride ...) but the tolerances are such that, sooner or later, you have to define an arbitrary compromise as "the standard" : I doubt that the length of my foot is exactly "1 foot".


So these imperial units are just as arbitrary as the SI units. And being able to visualise them ? I can vusualize 1 meter. Noit in terms of a fraction of a wave of light, but in a distance like "from here to there, or thereabouts". I think it just depends on the words you are given when you learn distances.

That's true, especially when you're not paying attention to the orders of magnitude of your calculations or don't really understand how decimal points work.

Indeed, I don't disagree - but I still prefer imperial and at least the term foot gives one a rough idea of the order of the metric i.e a mental visual comparison.

Yup, related to how long an arrow was or how much land an oxen could plough in a day etc etc They seem illogical but when you understand the system, it was amazing the way they all fitted together.

assuming a bit more than 3ft ~ 1 meter I'd expect something near 3 * 3 * 6 ~ 60 so I'll assume it's correct. How do you do it ? do you break it down in L x W x H , convert those, than multiply them to get volume, or do you just go 'cubic meter to cubic feet is multiply by 35.and add change ...) ?

They seem illogical but when you understand the system, it was amazing the way they all fitted together.
I've been wondering about that.
A lot of it seemse based on a factor 12,
and at one point it occured to me that eg the fractions of an inch always seem to be 1/4 - 3/8 - 1/2 - 5/8 - 3/4 - 15/16 - they always looked pretty random to me until I realized they're actually steps of 1/8 or 2/16 (wel; more ore less) and that eg a 1 and 15/16 inch pipe would pass nicely through a 2 inch hole.

But that's all the logic I see. Is there anything more to it ? I'm curious. (and I'd hate having to do calculations with those fractions)
