Supported Units
Decipad supports the following units and compositions of them. Unless stated, units default to the international standard.
For example, when we say Inch we mean Inch (International), i.e. 0.0254 m.
All definitions are exact.
Some conversions (e.g. bohr radius) are not exact by definition.
Please bear that in mind when using our units. Approximations are marked with a * for your convenience
