Where do you use division in carpentry? My understanding is that it primarily deals with adding up or subtracting to some length, since you must nearly always account for thickness. In that sense, it doesn't really matter if you use inches or centimeters, since you never convert units and never do any calculation that is more complicated than plus or minus.
AFAIK, IKEA uses millimeters, for example.
Bootstrap CSS doesn't seem all that relevant to the metric vs standard debate either, since it's neither of them. Time and angles are also divisible by twelve, for example.
- spenczar5 6y agoYou use division when coming up with even intervals. For example, "nail this panel to that board at 3 evenly-spaced locations." This shows up in joinery, too. That said, I do a lot of carpentry and woodworking, and have switched entirely to metric. I find it a lot easier to do addition and subtraction, as you say, but mostly it's more calculator-friendly. Adding ((273mm / 2) + 60.5mm + 546mm) is a lot easier to punch into a calculator than ((10 and 3/4 inches) / 2) + (2 and 7/8 inches) + (1 foot and 9 and 1/2 inches).
- waynesonfire 6y agoThe HP 35s Scientific Calculator is a fantastic calculator and has fractional arithmetic support. I reach for it in the shop frequently.
- spenczar5 6y agoHey, that’s a great tip, thanks! I still have to use inches sometimes, so I’ve just ordered that calculator.
- waynesonfire 6y agoNice! I think you'll like it. One thing, hope you noticed that it's an RPN calculator... takes a short amount of time to get adjusted to but is superior to algebraic entry. Here is an expanded manual on working with fractions: http://h20331.www2.hp.com/Hpsub/downloads/35_15_Working_with_Fractions.pdf http://h20331.www2.hp.com/Hpsub/downloads/35_15_Working_with... If you want to play with the HP family of calculators that are RPN check out Free42 (Android, Mac, and Windows emulator for a classic HP calculator. Note, it doesn't do fractions like the 35s) https://thomasokken.com/free42/ https://thomasokken.com/free42/
