Meters to Nanometers converter

To convert meters to nanometers, enter the value in the first field. The result in nanometers is calculated automatically using the exact conversion factor.

1 m = 1000000000 nm
1 nm = 1 × 10^-9 m

Formula: nm = m × 1000000000
m = nm × 1 × 10^-9

Definitions: 1 nm = 1 × 10^-9 m

The meter (m) is the SI base unit of length, defined by the distance light travels in a vacuum in 1/299,792,458 of a second. It is used for heights, room dimensions, running tracks and swimming pools.

The nanometer (nm) is one billionth of a meter. It is the unit for wavelengths of light (visible light spans roughly 400 to 700 nm), for features on semiconductor chips and for the size of viruses and molecules.
