About these units
Millimeter (mm)
- Definition
- A millimeter (mm) is one thousandth of a meter, used where small, precise measurements are needed.
- History
- Like other metric subdivisions it was defined in the 1790s using the prefix "milli-" (one thousandth).
- Current use
- Engineers, machinists, and manufacturers specify tolerances in millimeters, and rainfall is commonly reported in mm.
Nanometer (nm)
- Definition
- A nanometer (nm) is one billionth of a meter, the scale of atoms, molecules, and wavelengths of light.
- History
- It combines the SI prefix "nano-" (one billionth) with the meter and became common with the rise of nanotechnology.
- Current use
- Nanometers measure the wavelengths of visible light (about 380–750 nm) and the feature sizes of modern microchips.
