? i don’t know about you, but multiplying 19" times 25.4 isnt something easy at all to do quickly in your head. Also, not to mention the best example: when i have to convert cm to m I move the comma
when I have to convert from cm to freedom units: -Divide the height in centimeters by 30.48 and write down the whole number as feet
-Multiply the decimal part of the above division by 12
-Round the result of the multiplication to the nearest whole number and write it down as inches
like, really? you have to use two different units added together for one thing? How is that easy?
