Micrometer (µm) — SI unit equal to one millionth of a meter
Used in precision engineering, microscopy, and semiconductor manufacturing for dimensions far below a millimeter
- Symbol: µm (also called micron)
- System: SI derived unit
- Exact relations: 1 µm = 10⁻⁶ m = 0.001 mm = 10⁻⁴ cm
- Imperial/US equivalents: 1 µm ≈ 0.0000393700787 in
- Typical examples: human hair ~70 µm; bacteria ~1–10 µm; semiconductor features in the sub-µm to tens of µm range
Kilometer (km) — SI unit of length equal to 1,000 meters
Used worldwide for road distances, mapping, and athletics. In the metric system it scales cleanly with meters and centimeters for everyday to large-scale measurements.
- Symbol: km
- System: SI derived unit
- Exact relations: 1 km = 1,000 m = 10⁵ cm = 10⁶ mm
- Imperial/US equivalents: 1 km ≈ 0.621371 mi ≈ 3,280.8399 ft ≈ 1,093.6133 yd
- Typical examples: intercity travel; 5 km and 10 km races
