About energy conversions

Convert work, heat, and electrical energy. Calories use the thermochemical convention; BTU uses the international table.

Each unit is defined relative to one common base unit, so the same factors work consistently in both directions. Select any unit above to see its conversion formula, a worked example, and a reference table.
