Converter
Type a value and a unit — the unit is always required, never guessed. Add a material (1 L diesel), a target (1 kWh to MJ), a duration (5 kW for 3 h), your price (1000 kWh at 0.32 EUR/kWh) or your appliance's efficiency (100 kWh at 3.5 COP). Results are grouped by kind, each tagged with how exact it is.
Every result carries a label — exact, standard definition, source-based, estimate, or a prompt for the context it still needs. See what the labels mean →
