| 1 nm | 1e-9 m |
| 5 nm | 5e-9 m |
| 10 nm | 1e-8 m |
| 100 nm | 1e-7 m |
One nanometer equals 1.0000e-9 meters (m). To convert nanometers to meters, multiply by 1.0000e-9; to go back the other way, multiply by 1000000000 instead.
The converter above does it as you type and shows the working underneath, so you can check the arithmetic rather than take the number on trust.
What nanometers and meters actually measure
Nanometer (nm) — A nanometre is a billionth of a metre. Wavelengths of light, semiconductor process sizes and molecular dimensions.
Meter (m) — The metre is the SI base unit of length, defined by the distance light travels in 1/299,792,458 of a second. Room sizes, fabric, athletics tracks and almost all scientific work.

How to convert nanometers to meters by hand
Multiply the number of nanometers by 1.0000e-9.
For example, 25 nm × 1.0000e-9 = 2.5000e-8 m.
Going the other way, divide by 1.0000e-9 — or multiply by 1000000000, which is the same thing and easier to do in your head.
Everything runs in your browser
There is no server involved in the calculation. The numbers you type never leave your device, nothing is logged, and the page keeps working with no connection once it has loaded. That is not a marketing line — it is simply how the tool is built, because a calculation like this has no reason to touch a network.
Questions people ask
