Convert 1250 BTU/lb to J/kg

Understanding the Units

BTU/lb: British Thermal Unit per pound, a unit of energy per unit mass used in the United States and other countries.
J/kg: Joule per kilogram, a unit of energy per unit mass used in the International System of Units (SI).

Conversion Formula

To convert BTU/lb to J/kg, use the following formula:

1 BTU/lb = 2326 J/kg

Conversion Steps

Multiply the BTU/lb value by 2326:

1250 BTU/lb x 2326 J/kg = 2,907,500 J/kg

Applications

Converting from BTU/lb to J/kg is useful in various applications, including:
