Acceleration

Metric

Milimeter per (second squared) mm/s²
Galileo, or gal, or centimeter per (second squared) Gal, or cm/s²
A unit of acceleration used extensively in the science of gravimetry

Metre [or meter] per (second squared)
SI unit
m/s²
Since the newton equals one kilogram metre per second squared, the unit can also be written as the newton per kilogram, N·kg-1, or N/kg

Kilometer per (second squared) km/s²

TIP: Double-click any input field to clear the form

British (Imperial) and U.S. System

Inch per (second squared) in/s²
Foot per (second squared) ft/s²
Mile per (second squared) mi/s²

Gravity / Free Fall

G-force, Earth's Moon g moon
G-force, Mars g mars
G-force, Venus g venus
G-force, Earth, standard g
The g-force experienced by an object is its acceleration relative to free-fall

G-force, Sun g sun
Assuming that it actually had a surface

Unit converter & calculator mini-howto

Every input field works as a calculator. You can use the methods and constants (case sensitive!) described on this page.

Example 1
250 * 2

Example 2
(200 - 25) * (2 / 3)

Example 3
PI * pow(10, 3) + 5 * cos(2 * PI)

Example 4
5.0125e-5 * E

The result is calculated instantly (as you type) and displayed under the input field. The message syntax will appear when the expression is not understood (or incomplete).
