To convert a measurement in british thermal units to a measurement in megacalories, multiply the energy by the following conversion ratio: 0.000252 megacalories/british thermal unit.

Since one british thermal unit is equal to 0.000252 megacalories, you can use this simple formula to convert:

megacalories = british thermal units × 0.000252

The energy in megacalories is equal to the energy in british thermal units multiplied by 0.000252.

For example, here's how to convert 5,000 british thermal units to megacalories using the formula above.
megacalories = (5,000 BTU × 0.000252) = 1.260822 Mcal

British thermal units and megacalories are both units used to measure energy. Keep reading to learn more about each unit of measure.

What is a British Thermal Unit?
