Does 1 nanometer equals 0.00001

Answer 1

No.

1nm is a measure of length whereas 0.00001 is just some number which could be attached to any units to give some measure, eg 0.00001 g is a measure of weight, 0.00001 ha is a measure of area, etc.

However, the "nano-" prefix means 10-9 or 0.000000001, so

1 nm = 1 x (0.000000001 m)
= 0.000000001 m

= 0.000001 x (0.001 m)
= 0.000001 mm (since the "milli-" prefix(m) means 10-3 = 0.001)
= 0.001 x (0.000001 m)
= 0.001 µm (since the "micro-" prefix (µ) means 10-6 = 0.000001)
