Energy, pressure and power converter

Convert compatible units using explicit physical definitions.

How it works and limits

Choose units in the same dimension: energy, pressure or power. 1 kWh = 3,600,000 J; 1 thermochemical kcal = 4,184 J; 1 bar = 100,000 Pa. Mechanical horsepower uses 550 ft·lbf/s. This converts quantities only; it does not certify structural or equipment safety.
