Enter a value in any field to see all units update. Meters (m) Micrometers (µm or microns) Nanometers (nm) Scientific Notation (in Meters) - How to Convert Meters to Nanometers The conversion between meters (m) and nanometers (nm) is a simple factor of one billion (a 1 followed by nine zeros). This conversion is fundamental in fields like physics, nanotechnology, and optics. The Conversion Formula The relationship is based on the prefixes "micro-" (millionth) and "nano-" (billionth): 1 Meter (m) = 1,000,000,000 Nanometers (nm) 1 Meter (m) = 10 9 nm Therefore, to convert from meters to nanometers, you **multiply the meter value by 1,000,000,000**. To convert from nanometers to meters, you **divide the nanometer value by 1,000,000,000** (or multiply by 10 -9 ). The Scale of Metric Prefixes Understanding the "steps" from human scale (meters) down to the nano-scale is key. Each of these units is 1,000 times smaller than the one before it. Unit Symbol In Meters (Scientific) Example Meter m 1 m (10 0 m) Human height Millimeter mm 0.001 m (10 -3 m) Tip of a pencil Micrometer µm 0.000001 m (10 -6 m) Bacteria, water droplet Nanometer nm 0.000000001 m (10 -9 m) DNA strand, microchip circuits Angstrom Å 0.0000000001 m (10 -10 m) Atom size, chemical bonds Frequently Asked Questions (FAQ) How many nanometers are in a meter? There are **one billion (1,000,000,000)** nanometers in one meter. In scientific notation, this is written as 10 9 nm. What is 1 nanometer in meters? 1 nanometer (nm) is equal to one-billionth of a meter. As a decimal, this is 0.000000001 m. In scientific notation, it's written as 1×10 -9 m or 1e-9 m. What are nanometers used to measure? Nanometers are used to measure things on an atomic or molecular scale. This includes the wavelength of visible light (approx. 400-700 nm), the width of a strand of DNA (about 2.5 nm), and the tiny transistors on a computer chip (which can be smaller than 10 nm).
