Use this converter when the source value, representation, or measurement unit is known and you need the equivalent value in a supported target form without changing its underlying meaning.

Value

Must be greater than zero because L/100 km is reciprocal.

From unit

Required string input.

To unit

Required string input.

Convert positive vehicle efficiency and reciprocal fuel-consumption values among km/L, L/100 km, US mpg, and Imperial mpg. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Converted value

The resulting converted value returned as a number.

Unit

The resulting unit returned as a string.

• A conversion is only valid when the input convention is identified correctly. Unit systems, character encodings, byte order, color profiles, reference conditions, rounding, and calendar or time-zone rules can make superficially similar values non-equivalent.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Keep the original value and its unit or encoding alongside the result. For interchange, also validate the output against the receiving format, standard, color profile, or reference conditions.
