How to convert International Table Btu to electronvolts

Calories use the thermochemical definition. Btu use the International Table definition. Food Calories are kilocalories, not single calories.

Use x for the value in Btu IT, b for the intermediate value in J, and y for the result in eV.

eV = Btu IT × 1055.05585262 ÷ 1.602176634e-19

Worked examples

  • 10 Btu IT ≈ 6.58514067819e+22 eV

    Step 1: (10 × 1055.05585262) ≈ 10550.5585262 J.
    Step 2: 10550.5585262 ÷ 1.602176634e-19 ≈ 6.58514067819e+22 eV.

  • 20 Btu IT ≈ 1.31702813564e+23 eV

    Step 1: (20 × 1055.05585262) ≈ 21101.1170524 J.
    Step 2: 21101.1170524 ÷ 1.602176634e-19 ≈ 1.31702813564e+23 eV.

Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.

About International Table Btu

International Table Btu (Btu IT) measures energy under the conventions above. The base value in J is (x × 1055.05585262), where x is the numerical value in Btu IT. Factors shown here are rounded for display; calculations use the stored factor.

About Electronvolts

Electronvolts (eV) measures energy under the conventions above. The base value in J is (x × 1.602176634e-19), where x is the numerical value in eV. Factors shown here are rounded for display; calculations use the stored factor.
