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 (nm) - How to Convert Nanometers to Micrometers The conversion between nanometers (nm) and micrometers (µm) is a simple factor of 1000. These units are essential in science and engineering for measuring microscopic and nanoscopic objects. The Conversion Formula The relationship is based on the metric prefixes "micro-" (one-millionth) and "nano-" (one-billionth). 1 Micrometer (µm) = 1,000 Nanometers (nm) Therefore, to convert from nanometers to micrometers, you **divide the nanometer value by 1,000**. Formula: µm = nm
