Conversion Table
You can use the
Custom Converter
to create your own list of units. Derived units will be automatically created based on the prefix(es) you choose below.
A base unit is a unit that cannot be expressed in terms of other units. For example: "meter" is a base unit and "kilometer" is a derived unit, since it is derived from "meter".
Please note that units marked in red are not derivable.
