1. What is a BTUs to Tons Cooling Calculator?

Definition: This calculator converts cooling capacity from BTU/h (British Thermal Units per hour) to tons of refrigeration.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Tons of cooling
• \( Q \) — Cooling capacity in BTU/h

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

3. Importance of the Conversion

Details: Understanding both units is essential for equipment sizing, system design, and comparing cooling capacities across different systems.

4. Using the Calculator

Tips: Simply enter the cooling capacity in BTU/h. The calculator will automatically compute the equivalent tons of cooling.

5. Frequently Asked Questions (FAQ)

Q1: Why is 12,000 BTU/h equal to one ton?
A: This originates from the amount of heat needed to melt one ton (2000 lbs) of ice in 24 hours.

Q2: What's a typical residential AC unit size?
A: Most homes have 1.5 to 5 ton units (18,000 to 60,000 BTU/h).

Q3: How do I find my system's BTU rating?
A: Check the equipment nameplate or manufacturer specifications.

Q4: Is this conversion exact?
A: Yes, the 12,000:1 ratio is the standard definition in the HVAC industry.

Q5: Can I convert tons back to BTU/h?
A: Yes, simply multiply tons by 12,000 to get BTU/h.
