Acceleration

Lower-case g as acceleration (9.80665 m/s²) is not the gram. In engineering g usually means standard gravity; in commerce it means gram. Acceleration appears in physics, vehicle engineering and sensor datasheets.

Factor origin

Factors come from the stored source family and are not derived from rounded display values.

Rounding rule

UnitCloud keeps calculating with stored factors and rounds only the displayed output by selected precision.

When not to use

Do not use as the sole basis for official, medical, safety-critical or contractual decisions.
