nm to M Converter
Convert nanometers to meters and back. A nanometer is one billionth of a meter (1 nm = 1e-9 m) — enter nm (or switch to meters) for meters, microns, and angstroms. Newton-meters are a different unit.
Example: with Value 500 · Direction Nanometers → Meters → Result: 5.0000e-7 m.
- Microns and angstroms0.5 µm · 5,000 Å
- Conversion500 nm = 5.0000e-7 m
Computed by the calculator below using its default values. Change any input to see your own numbers.
1 nm = 1e-9 m (a billionth of a meter). Lowercase nm is a length; capital N-m (newton-meter) is torque and is a completely different quantity.
Down at the billionth-of-a-meter scale
A nanometer is one billionth of a meter, the scale of molecules, virus particles, and semiconductor features. Converting to meters means multiplying by 1e-9, which is why the meter values look like tiny scientific-notation numbers: 500 nm is 5e-7 m.
Watch the notation trap. Written casually, nm means nanometer, but Nm with a capital N means newton-meter, a completely different quantity used for torque or energy. This tool is strictly about length. For tightening bolts and engine specs, reach for a newton-meter torque converter instead.
How it’s calculated
meters = nm × 1e-9; nm = meters × 1e9. Related outputs use 1 nm = 1e-3 µm = 10 angstrom (Å). Results in meters are shown in scientific notation because they are very small.
Concerns the nanometer (a length). It does not handle the newton-meter (Nm), which measures torque or energy.
Nanometers to meters
| Nanometers | Meters | Also |
|---|---|---|
| 1 nm | 1e-9 m | 10 Å |
| 100 nm | 1e-7 m | 0.1 µm |
| 500 nm | 5e-7 m | green light |
| 1,000 nm | 1e-6 m | 1 µm |
| 1,000,000 nm | 0.001 m | 1 mm |
Computed as meters = nm × 1e-9; 1 nm = 10 angstrom = 0.001 µm.
Common mistakes
- Confusing nm the length (nanometer) with Nm the torque (newton-meter) — use a torque tool for Nm.
- Losing exponents: 500 nm is 5e-7 m, not 5e-9 m.
- Mixing nanometers and micrometers; 1,000 nm make 1 µm.
Frequently asked questions
How many meters is a nanometer?
One nanometer is 1e-9 meter, a billionth of a meter. So 500 nm is 5e-7 m.
Is nm the same as Nm (newton-meter)?
No. Lowercase nm is a nanometer, a length. Capital N-m is a newton-meter, a unit of torque or energy. They are unrelated, so use a torque converter for Nm.
How do I convert nm to meters?
Multiply by 1e-9, which moves the decimal nine places to the left. To go from meters to nanometers, multiply by 1e9.
What is a nanometer in angstroms or microns?
1 nm = 10 angstrom and 0.001 micrometer (µm). Visible light runs about 380 to 700 nm.
