1. What is BTU Calculation?

BTU (British Thermal Unit) calculation helps determine the appropriate air conditioner size for a given space. Proper sizing ensures efficient cooling and energy savings.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Area \) — Room area in square feet
• \( Factor \) — BTU per square foot factor (typically 20 BTU/sq ft for standard rooms)

Explanation: The factor accounts for typical cooling requirements per square foot and may need adjustment for special conditions.

3. Importance of Proper AC Sizing

Details: Correct BTU calculation prevents energy waste from oversized units and insufficient cooling from undersized units. Proper sizing extends equipment life and improves comfort.

4. Using the Calculator

Tips: Measure your room dimensions accurately. Standard factor is 20 BTU/sq ft, but increase for sunny rooms (×1.1), kitchens (×1.4), or crowded spaces (×1.2).

5. Frequently Asked Questions (FAQ)

Q1: What's the standard BTU per square foot?
A: Typically 20 BTU/sq ft for standard rooms with 8-foot ceilings and normal conditions.

Q2: How do I adjust for room height?
A: For ceilings higher than 8 feet, multiply the result by (ceiling height ÷ 8).

Q3: What about windows and insulation?
A: Poor insulation or many windows may require increasing the factor by 10-20%.

Q4: Is this calculation for central AC or window units?
A: The principle applies to both, though central AC requires whole-house calculations.

Q5: What if my room is irregularly shaped?
A: Divide into rectangular sections, calculate each separately, then sum the BTUs.
