How to Convert BTU/Pound-°F to Kilocalorie/Kilogram-°C

To convert from BTU/Pound-°F (BTU/(lb·°F)) to Kilocalorie/Kilogram-°C (kcal/(kg·°C)), multiply the value by 1.0006692161.

Formula: kcal/(kg·°C) = BTU/(lb·°F) × 1.0006692161

Reverse: BTU/(lb·°F) = kcal/(kg·°C) × 0.9993312315

Step-by-Step Example

Start with your value in BTU/Pound-°F. For example: 5 BTU/(lb·°F)
Multiply by the conversion factor: 5 x 1.0006692161
The result is: 5.003346 kcal/(kg·°C)
