1. What is BTU/hr to Tons Cooling Conversion?

Definition: This calculator converts cooling capacity from BTU per hour to tons of refrigeration.

Purpose: It helps HVAC professionals and engineers convert between these common cooling capacity units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Tons of cooling
• \( Q \) — Cooling capacity in BTU per hour

Explanation: One ton of cooling equals 12,000 BTU/hour, so we divide the BTU value by 12,000 to get tons.

3. Importance of This Conversion

Details: HVAC systems are often rated in tons, while heat loads are calculated in BTU/hr. This conversion bridges these measurement systems.

4. Using the Calculator

Tips: Simply enter the BTU per hour value. The calculator will automatically compute the equivalent tons of cooling.

5. Frequently Asked Questions (FAQ)

Q1: Why is 12,000 BTU equal to 1 ton?
A: This originates from the amount of heat needed to melt one ton of ice in 24 hours (288,000 BTU/24h = 12,000 BTU/h).

Q2: Is this conversion exact?
A: Yes, the 12,000 BTU/h = 1 ton relationship is a defined standard in the refrigeration industry.

Q3: What's a typical residential AC unit size?
A: Most homes have 1.5-5 ton units (18,000-60,000 BTU/h).

Q4: How do I find my system's BTU rating?
A: Check the manufacturer's plate or documentation, or calculate from other specifications.

Q5: Does this apply to both heating and cooling?
A: While the ton unit is primarily for cooling, the conversion works for any BTU/h value.
