Centimetres to nanometres converter
Nanometres (nm)
1 centimetre = 10,000,000 nanometres
How to convert centimetres to nanometres
nm = cm × 10000000
Multiply the number of centimetres by 10000000 to get nanometres. Going the other way, divide by 10000000 (or multiply by 1 × 10^-7).
One centimetre is exactly defined as 10000000 nanometres (to 12 significant figures), and one nanometre is 1 × 10^-7 centimetres.
Worked examples
- Convert 5 centimetres: 5 × 10000000 = 50,000,000 50,000,000 nanometres.
- Convert 12.5 centimetres: 12.5 × 10000000 = 125,000,000 125,000,000 nanometres.
- Convert 250 centimetres: 250 × 10000000 = 2,500,000,000 2,500,000,000 nanometres.
