Metres to nanometres converter
Nanometres (nm)
1 metre = 1,000,000,000 nanometres
How to convert metres to nanometres
nm = m × 1000000000
Multiply the number of metres by 1000000000 to get nanometres. Going the other way, divide by 1000000000 (or multiply by 1 × 10^-9).
One metre is exactly defined as 1000000000 nanometres (to 12 significant figures), and one nanometre is 1 × 10^-9 metres.
Worked examples
- Convert 5 metres: 5 × 1000000000 = 5,000,000,000 5,000,000,000 nanometres.
- Convert 12.5 metres: 12.5 × 1000000000 = 12,500,000,000 12,500,000,000 nanometres.
- Convert 250 metres: 250 × 1000000000 = 250,000,000,000 250,000,000,000 nanometres.
