Convert joules (J), calories (cal), kilowatt-hours (kWh), BTU, and other energy units. Energy is the capacity to do work; the joule (J) is the SI unit (1 J = 1 N·m). Nutritional calories and electrical kWh use different reference definitions tied to joules.
This energy converter transforms values from Joules (J) to Btu (BTU). Results update instantly using the exact conversion factor.
The joule (J) is the SI unit of energy (1 J = 1 N·m).
The Btu (BTU) is a unit of energy in the Energy category.
1 J ÷ 1055.05585262 = 0.000948 BTU
BTU = J ÷ 1055.05585262
To convert J to BTU, divide the value in J by 1055.05585262 (since 1 J = 0.000948 BTU). Equivalently, multiply by 0.000948. Example: 1 J = 1 J × 0.000948 = 0.000948 BTU.
10 J = 0.009478 BTU ÷ 1055.05585262 = 10 J
