Question

Why is unit conversions in chemistry category and not in some other subject? like converting mm to cm.These are not a part of chemistry though.......

Answer 1

I have always found unit conversions to be difficult in all subjects...

Explanation:

For units of volume we use `1*L`, `1000*mL`, `1000*cm^3`, `1*dm^3`, AND ALL of these are the same volume. Chemistry sometimes uses non standard units of length, i.e. `1*"Angstrom"` `-=` `1xx10^-10*m`, and this is a HIGHLY useful unit - all structural chemists would think in terms of `"angstroms"`.
