1 metre = 1,000 mm 1 mm = 0.001 metre 2 mm = 0.002 metre
assuming 1 is 1 metre which is 100cm or 1,000mm then 15cm is 15/100 = 15% of 1 metre
1 metre is a length or distance measure and 1 square metre is an area. One cannot be converted to the other.

A nanometre is a linear length equivalent to one billionth of a metre.
A nanometer is about one billionth of a metre (0.000000001 meters)
A nanometre is equal to one billionth of a metre. Therefore, 20 nanometres is equal to 20 billionths of a metre.
1 nanometre equals one billionth (10-9) of a metre.
