It's not english, latin, greek, french, or spanish. I give up. Lord of the rings Elvish, or did someone hack your account?

I support this idea, even though it is already do-able. Perhaps a more simple way of doing this would be great.

Wow, talk about a polarized thread. The long and the short of it is that imperial units are fractional, and founded on arbitrary units (how big is the kings foot, etc). The only current measurement system that I can think of that is older and makes less sense are the time and angle systems, also based on fractions. Between 1 and 100, 60 is the number with the most factors. Fractional systems have a place, as my drafting teach would say, how accurate you are depends on your sharpest pencil. I can measure an inch, ok, cut it in half, and in half, and in half, and again, is your pencil sharp enough to cut it in half again? This is great for scaling recipes, or keeping the accuracy of measurement neatly encoded into your dimensions, but for calculations it just plain sucks. There are lots of time that I would rather write something in a fractional way, and 1 5/8 m is just ridiculous. Almost as ridiculous as me telling you I have a marble that is 6.214 x 10^-6 miles .

Sense Algodoo is currently rounding the display of measurements but keeps track more accurately internally, a single layer of abstraction would allow for unit shifting. Keep all the math in metric, and have it look up a conversion coefficient for the unit desired.

Now for the other side of things. Anyone who wants to defend their use of the imperial system should know ALL of their basic conversions, both inside the imperial system, and to metric. 5ml to the teaspoon, 3 teaspoons to the tablespoon, almost 4 liters in a gallon, a little more than two and a half cm to the inch, 5280 ft to the mile, etc. Everything in my kitchen is purposefully dual unit, and unless i am doubling or halving a recipe i convert it to metric as the first step. My wood shop is still mostly imperial, because I live in the USA, and it is what is most available. Almost all of my metal tools are metric or dual unit because I have to order all of them online anyway. The US is the only country that feeds more then 3/4 of its people and still uses the imperial system, if you haven't learned its basics, think of it as a step towards understanding the rest of the world.

small note: I would also like to see a way to easily (without scripting) set the dimensions of boxes and circles, and then later easily edit those shapes. Displaying Imperial units would be nice on occasion, but it isn't that hard to convert, and it is a rare physics mock up that I am doing that will later be built out of wood (the marble clock I'm working on right now would be the exception.)

so there are my 0.02USD

i all i want is an option to make things displayed in the imperial system and a system to put your dimensions into something and make a box

Great first post.

Actually, I think that the imputting dimensions is good, but not the impereial system. still, you can just use the grid!!!
