Instantly convert between **nanometers (nm)**, **micrometers (µm)**, **millimeters (mm)**, and **meters (m)** by entering a value in any field. Nanometers (nm) Micrometers (µm or microns) Millimeters (mm) Meters (m) Nanometers in Scientific Notation - How to Convert Nanometers to Meters The conversion between nanometers (nm) and meters (m) is a simple base-10 relationship. A nanometer is one-billionth of a meter. The Conversion Formula The relationship is defined as: 1 Meter (m) = 1,000,000,000 Nanometers (nm) 1 Nanometer (nm) = 0.000000001 Meters (m) In scientific notation, this is much easier to write: 1 nm = 1×10 -9 m Therefore, to convert from nanometers to meters, you **divide the nanometer value by 1,000,000,000** (one billion). Formula: m = nm
