Ton to Watt: The Essentials
About the Ton
Ton (ton) is a unit of power measurement. 1 ton is equal to 3516.8528421 watt.
About the Watt
Watt (W) is a unit of power measurement. 1 watt is equal to 0.0002843 ton.
Power Measurement Across Applications
Power units span from milliwatts in electronics to megawatts in power plants. Engine output is still quoted in horsepower (mechanical, metric, and electrical — all slightly different). HVAC systems rate cooling in tons of refrigeration or BTU/hour. Solar panels specify watts peak. Electric motors list watts or kilowatts. Each industry carries its historical unit preferences, making conversion between them a daily necessity.

How to Convert TON to W (Ton to Watt)?
We can convert ton to watt by using an example.
Example:
Convert 20 Ton to Watt?
We know 1 Ton = 3516.8528421 watt; 1 Watt = 0.0002843 ton.
20 ton = ___W
20 × 3516.8528421 = 70337.05684 W (we know 1 ton = 3516.8528421 watt)
Answer:
20 ton = 70337.05684 watt
Tons of Refrigeration to Watts: HVAC System Sizing
In HVAC engineering, cooling capacity is measured in "tons of refrigeration." One ton equals the cooling effect of melting one short ton (2,000 lb) of ice in 24 hours — which works out to 3,516.85 watts of heat removal. This unit is standard in North American air conditioning, where a "3-ton unit" means it removes heat at a rate of about 10,550 watts.
- Identify the cooling capacity in tons of refrigeration.
- Multiply by 3,516.85 to get watts of cooling capacity.
- For kilowatts, divide the result by 1,000 (or multiply tons by 3.517).
- This represents heat removal rate, not electrical consumption.

Answer: 3.5 tons = 12,309 W (12.3 kW) of cooling capacity.
Question 2: A server room requires 20 tons of cooling. Express in watts.
Solution:
Watts = tons × 3,516.85
= 20 × 3,516.85

Answer: 20 tons = 70,337 W (70.3 kW) of heat removal capacity.
Question 3: A chilled water plant is rated at 200 tons. Convert to watts.
Solution:
Watts = tons × 3,516.85
= 200 × 3,516.85
= 703,370 W
Answer: 200 tons = 703,370 W = 703.4 kW cooling capacity.

Cooling Capacity vs. Electrical Consumption
A 3-ton AC unit provides 10,551 W of cooling but does NOT consume 10,551 W of electricity. Modern systems have a Coefficient of Performance (COP) of 3-5, meaning they move 3-5 watts of heat for every watt of electricity consumed. A 3-ton unit with COP 4 consumes only about 2,638 W (10,551 ÷ 4) of electrical power. The SEER rating on US units measures seasonal efficiency.
Why HVAC Uses "Tons" in North America
Before mechanical refrigeration, buildings were cooled with ice harvested from frozen lakes. The "ton" unit preserves this heritage: melting 2,000 lb (one short ton) of ice at 0°C absorbs 288,000 BTU over 24 hours = 12,000 BTU/hr = 3,516.85 watts. While the rest of the world uses kW for cooling, North American HVAC contractors still size systems in tons because codes, ductwork tables, and equipment catalogs use this unit.
Key Takeaways
- 1 ton of refrigeration = 3,516.85 watts of cooling capacity.
- This measures heat removal rate, not electrical consumption.
- COP of 3-5 means electrical draw is 1/3 to 1/5 of cooling capacity.
- Residential rule of thumb: 1 ton per 500 sq ft in moderate climates.
- The unit comes from ice-harvesting days (1 ton of ice melted in 24 hours).
