Calculation Formula

BTU = 1.05 * (Area * Height) * (Temperature Change) * (Insulation Factor)

Where:
Area = Room Area (sq ft)
Height = Ceiling Height (ft)
Temperature Change = Desired Temperature Change (°F)
Insulation Factor = 11 - Insulation Rating

Air Conditioner British Thermal Unit Calculator Calculator Usage Guide

Learn how to use the Air Conditioner British Thermal Unit Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the room area in square feet.
  2. Enter the ceiling height in feet.
  3. Enter the insulation rating on a scale of 1 to 10 (1 being poor insulation, 10 being excellent insulation).
  4. Enter the desired temperature change in degrees Fahrenheit.
  5. Click the "Calculate" button to determine the required BTU for the air conditioner.

Understanding the Formula

The calculator uses the following formula to determine the required BTU:

BTU = 1.05 * (Area * Height) * (Temperature Change) * (Insulation Factor)

Where:

  • Area is the room area in square feet.
  • Height is the ceiling height in feet.
  • Temperature Change is the desired temperature change in degrees Fahrenheit.
  • Insulation Factor is calculated as 11 minus the insulation rating.

Example

For a room with an area of 1,500 sq ft, a ceiling height of 8 ft, an insulation rating of 5, and a desired temperature change of 15°F, the calculation would be:

BTU = 1.05 * (1500 * 8) * 15 * (11 - 5) = 1.05 * 12000 * 15 * 6 = 113400 BTU

This means you would need an air conditioner with a cooling capacity of at least 113,400 BTU to cool this room.
