What is BTU Converter Calculator?

▾

BTU (British Thermal Unit) measures the amount of energy needed to raise one pound of water by 1°F. For air conditioning and heating, BTU/hr ratings indicate how much thermal energy a system can move per hour. The right BTU capacity prevents under-cooling (too weak) or short-cycling (too powerful).

How to BTU Converter Calculator

▾

1Start with 20 BTU per square foot of living space
2Adjust for ceiling height: multiply by height/8 (standard 8ft ceiling)
3Factor in climate zone, sun exposure, and number of occupants
4Add 600 BTU per person beyond two regular occupants

Worked Examples

▾

Example 1

Given:300 sq ft bedroom, 8ft ceiling, moderate climate

ಫಲಿತಾಂಶ:6,000 BTU (0.5 ton)

300 × 20 = 6,000 BTU

Example 2

Given:500 sq ft open plan, 10ft ceilings, sunny

ಫಲಿತಾಂಶ:~13,750 BTU (1.1 ton)

Height and sun adjustments add ~37%

Room Size to BTU Guide

▾

Room Size (sq ft)	BTU Needed	AC Tons
100–150	5,000	0.4
150–250	6,000	0.5
250–350	7,000	0.6
350–450	10,000	0.8
450–550	12,000	1.0
550–700	14,000	1.2
700–1,000	18,000	1.5
1,000–1,200	21,000	1.75
1,200–1,400	23,000	1.9
1,400–1,500	24,000	2.0

💡

Pro Tip

Oversizing is as bad as undersizing. A too-large AC cools fast but cycles off before removing humidity, leaving the room cold and clammy.

Did you know?

1 ton of air conditioning equals 12,000 BTU/hr — originally derived from the amount of cooling produced by melting one ton of ice over 24 hours.
