Btu (thermoc.) to Calories (Kilogram,thermoc.)

Btu (thermoc.)

The Btu (thermochemical) variant aligns with the thermochemical calorie and is defined as the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit at a constant pressure of one atmosphere and is equivalent to approximately 1,054.350 Joules.

Calories (Kilogram,thermoc.)

The kilogram calorie (also known as the large calorie, food calorie, or kilocalorie) is the energy to raise the temperature of one kilogram of water by one degree Celsius at a pressure of one atmosphere. This unit is widely used in nutrition to quantify the energy content of foods.
