BTU Per Hour Calculator

Formula

The formula to calculate the BTU per hour is:

\[ \text{BTU/hr} = (\text{W} \times 3.412141633) + (\text{HP} \times 2544.433) \]

Where:

\(\text{BTU/hr}\) is the British Thermal Units per hour
\(\text{W}\) is the power in watts
\(\text{HP}\) is the power in horsepower

What is BTU Per Hour?

BTU per hour (BTU/hr) is a unit of power used to describe the rate at which energy is used or produced. One BTU is the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit. When expressed as BTU per hour, it indicates the amount of energy transferred or consumed in one hour. This unit is commonly used in heating, ventilation, and air conditioning (HVAC) systems to measure the capacity of heating and cooling equipment.

Example Calculation 1

Let's assume the following values:

Power in Watts (W) = 1000 W
Power in Horsepower (HP) = 1 HP

Using the formula:

\[ \text{BTU/hr} = (1000 \times 3.412141633) + (1 \times 2544.433) = 3412.1416 + 2544.433 = 5956.5746 \text{ BTU/hr} \]

The BTU Per Hour is 5956.5746 BTU/hr.

Example Calculation 2

Let's assume the following values:

Power in Watts (W) = 2000 W
Power in Horsepower (HP) = 2 HP

Using the formula:

\[ \text{BTU/hr} = (2000 \times 3.412141633) + (2 \times 2544.433) = 6824.2833 + 5088.866 = 11913.1493 \text{ BTU/hr} \]

The BTU Per Hour is 11913.1493 BTU/hr.
