BTU Heat Load Calculator

Calculate the temperature rise in a room based on BTU output from equipment, servers, or HVAC systems.

What is BTU? British Thermal Unit (BTU) measures heat energy. One BTU is the energy needed to raise one pound of water by 1°F. Use this calculator to determine how equipment heat output affects room temperature.

Important Notes:
• This calculation assumes no ventilation or cooling system
• Air density: standard atmospheric conditions at sea level
• Heat capacity of air: 0.24 BTU per cubic foot per degree Fahrenheit
• For data centers, ensure adequate cooling to prevent temperature rise
• Continuous heat load will cause cumulative temperature increase without cooling
