1. What is Air Conditioner Tonnage?

Air conditioner tonnage refers to the cooling capacity of an AC unit. One ton of cooling equals 12,000 BTU (British Thermal Units) per hour. This measurement originates from the amount of heat needed to melt one ton of ice in 24 hours.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Tons \) — Cooling capacity in tons
• \( BTU/h \) — British Thermal Units per hour (input value)
• 12000 — Conversion factor (1 ton = 12,000 BTU/h)

Explanation: This calculation converts BTU per hour rating to standard tons of cooling capacity.

3. Importance of Proper Tonnage Calculation

Details: Correct tonnage calculation is essential for selecting an appropriately sized air conditioner. Undersized units won't cool effectively, while oversized units cycle too frequently, reducing efficiency and comfort.

4. Using the Calculator

Tips: Enter the BTU/h rating from your air conditioner's specifications or nameplate. The calculator will instantly convert this to tons of cooling capacity.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BTU and tons?
A: Tons are a larger unit of cooling capacity (1 ton = 12,000 BTU/h). Residential AC units are typically 1-5 tons.

Q2: How many BTU/h are in 1 ton?
A: There are exactly 12,000 BTU/h in 1 ton of cooling capacity.

Q3: What size AC do I need for my home?
A: While this calculator converts units, proper sizing requires a Manual J calculation considering square footage, insulation, climate, and other factors.

Q4: Can I use this for heat pumps?
A: Yes, the same conversion applies to heat pump cooling capacity ratings.

Q5: Why is proper sizing important?
A: Properly sized units operate more efficiently, last longer, and provide better humidity control and comfort.
