Formula and precision

Value in W = Value in kcal/h × 1.16222222
1 kcal/h is equal to 1.16222222 W.
Yes. Conversions run locally in your browser using verified ratios and display up to 8 decimals. Some categories like temperature and fuel use specialized formulas.
  • Use smaller units for higher precision, then convert back if needed.
  • Temperature and fuel categories can’t be reduced to one constant multiplier.
  • Symbols vary by region (US/UK gallons, metric vs. imperial abbreviations).
  • For engineering work, validate with a second reference and keep unit symbols.

Quick examples

Example: 1 kcal/h = 1.16222222 W.

Common mistakes and definitions

  • Rounding too early (convert first, then round at the end).
  • Mixing similar-looking symbols (for example, “m” vs “mm”, or “b” vs “B”).
  • Copying values without the unit symbol, which makes validation harder.
