# Calories (thermochemical) to Btu formula

Use the formula below to convert any value from calories (thermochemical) to Btu:

british thermal units = calories (thermochemical) × 0.0039656666533024

To from calories (thermochemical) to british thermal unit, you just need to multiply the value in calories (thermochemical) by 0.0039656666533024. (It is called the conversion factor)

## Using the formula (some examples):

Convert full calorie (thermochemical) to british thermal units:
a calorie (thermochemical) = 1 × 0.0039656666533024 = 0.0039656666533024 british thermal units.

Convert two calorie (thermochemical) to british thermal units:
two calorie (thermochemical) = 2 × 0.0039656666533024 = 0.0079313333066049 british thermal units.

Convert five calories (thermochemical) to british thermal units:
5 calories (thermochemical) = 5 × 0.0039656666533024 = 0.019828333266512 british thermal units.

## More Examples:

Convert ten calories (thermochemical) to british thermal units: 10 calories (thermochemical) = 10 × 0.0039656666533024 = 0.039656666533024 british thermal units.

Convert twenty calories (thermochemical) to british thermal units: 20 calories (thermochemical) = 20 × 0.0039656666533024 = 0.079313333066049 british thermal units.

Convert fifty calories (thermochemical) to british thermal units: 50 calories (thermochemical) = 50 × 0.0039656666533024 = 0.19828333266512 british thermal units.

Convert a hundred calories (thermochemical) to british thermal units: 100 calories (thermochemical) = 100 × 0.0039656666533024 = 0.39656666533024 british thermal units.

Convert a thousand calories (thermochemical) to british thermal units: 1000 calories (thermochemical) = 1000 × 0.0039656666533024 = 3.9656666533024 british thermal units.
