Btu/lbm-°F to kJ/kg-°C and kJ/kg-°C to Btu/lbm-°F Calculator

How to Calculate Between Btu/lbm-°F and kJ/kg-°C

The Btu/lbm-°F to kJ/kg-°C and kJ/kg-°C to Btu/lbm-°F Calculator converts between British Thermal Units per pound mass per degree Fahrenheit (Btu/lbm-°F) and kilojoules per kilogram per degree Celsius (kJ/kg-°C) for specific heat capacity in imperial and SI units. The formulas are:

\( kJ/kg \cdot ^\circ C = Btu/lbm \cdot ^\circ F \times 4.1868 \)
\( Btu/lbm \cdot ^\circ F = kJ/kg \cdot ^\circ C / 4.1868 \)

Where:

\( Btu/lbm \cdot ^\circ F \): British Thermal Units per pound mass per degree Fahrenheit, an imperial unit of specific heat.
\( kJ/kg \cdot ^\circ C \): Kilojoules per kilogram per degree Celsius, a SI unit of specific heat.

Select the conversion direction, enter the input value, and calculate the result.

Using the Btu/lbm-°F and kJ/kg-°C Mutual Conversion Calculator

This calculator is useful for thermodynamics, material science, or engineering, such as converting specific heat capacities, supporting bidirectional conversions.

Select the direction (Btu/lbm-°F to kJ/kg-°C or kJ/kg-°C to Btu/lbm-°F), input the value. The calculator outputs the converted value.

Example 1: For a specific heat of 1 Btu/lbm-°F to kJ/kg-°C.

Direction: Btu/lbm-°F to kJ/kg-°C
Input: \( 1 \)
Calculation: \( kJ/kg \cdot ^\circ C = 1 \times 4.1868 = 4.1868 \)
Result: \( 4.1868 \, \text{kJ/kg-°C} \)

Example 2: For a value of 4.1868 kJ/kg-°C to Btu/lbm-°F.

Direction: kJ/kg-°C to Btu/lbm-°F
Input: \( 4.1868 \)
Calculation: \( Btu/lbm \cdot ^\circ F = 4.1868 / 4.1868 = 1.0000 \)
Result: \( 1.0000 \, \text{Btu/lbm-°F} \)

Use this tool for quick bidirectional conversions in engineering analysis.
