How the conversion works

The input is converted into J using the source factor and offset, then into BTU international table. This keeps unit definitions consistent across the energy collection.

Definitions and sources

Factors are maintained in the versioned unit dataset. Output is rounded to your selected significant digits; calculation uses JavaScript double precision.

How to use this tool

  1. Enter a finite numeric value in kilojoule.
  2. Choose the significant digits for your result.
  3. Copy or download the result, including its formula.

Accuracy and scope

Calorie and BTU conventions are explicitly distinguished. Electronvolt uses the exact post-2019 SI elementary charge.
