Frequently Asked Questions

What is the SI base unit of angle?

The SI base angle unit is rad. Most conversions factor through it, except temperature which is affine and fuel-economy which is reciprocal.

Which unit systems are represented?

Angle includes both metric and imperial units (where they exist in this category). For mass and length, both metric (kg, m) and US customary (lb, ft) are listed. For temperature, the three most-common scales (Celsius, Fahrenheit, Kelvin) plus Rankine and Réaumur.

How accurate are these conversions?

Conversions use the standard SI factors (NIST values where applicable). Where two slightly different definitions exist (e.g. KB vs KiB, US vs UK gallon), they are listed as separate units rather than auto-rounded.

其他分類

#1
Length

Distance, height, width — anything that measures how long something is. SI base unit: the metre (m).

 #2
Mass

How much matter is in something. Differs from weight (which is force). SI base: kilogram (kg).

 #3
Temperature

How hot or cold something is. Conversions are affine — there is an offset, not just a multiplier.

 #4
Area

Size of a 2-D surface. SI base: square metre (m²).

 #5
Volume

Space occupied by a 3-D object. SI base: litre (L) for everyday use; cubic metre (m³) for SI.

 #6
Speed

Distance per unit time. SI: metre per second (m/s).

 #7
Time

Duration. SI base: the second (s).

 #8
Data

Digital information size. SI: the byte (B). Note the difference between decimal (KB=1000) and binary…

 #9
Energy

Capacity to do work. SI base: joule (J). Also commonly expressed as calories, kWh, BTU.

 #10
Pressure

Force per unit area. SI base: pascal (Pa).

 #11
Fuel Economy

Distance per unit of fuel, or its reciprocal (fuel per distance). Base: litres per 100 km.
