How do you convert tons of refrigeration to terawatts?

To convert tons of refrigeration (TR) to terawatts (TW), multiply the power in tons of refrigeration by 3.516853e-9 (terawatts = tons of refrigeration × 3.516853e-9).

What is 5 tons of refrigeration in terawatts?

5 tons of refrigeration (5 TR) is equal to 1.758426e-8 terawatts (1.758426e-8 TW).

Which is larger, 1 ton of refrigeration (tr) (TR) or 1 terawatt (TW)?

One terawatt (TW) is larger than one ton of refrigeration (tr) (TR). Specifically, 1 TW equals 284,345,136.0939925 TR, while 1 TR is 3.516853e-9 TW.

How do I convert back from terawatts (TW) to tons of refrigeration (TR)?

To reverse the calculation from TW to TR, multiply your terawatt value by the inverse factor 284,345,136.0939925 (or divide by 3.516853e-9). You can also click the Swap button in the tool above to flip directions in one click.

How many decimal places should I round TR to TW results to?

For everyday comparisons and quick estimates, rounding to 2 decimal places is usually sufficient (for example, 5 TR ≈ 0.00 TW). For engineering, laboratory, or machining specifications, select 4 or 6 decimals—or Scientific (10ⁿ) mode—in the calculator toolbar above.

How to Convert Tons of Refrigeration to Terawatts

To convert tons of refrigeration to terawatts, multiply the power by the following conversion ratio: 3.516853e-9 terawatts/ton of refrigeration.

Since one ton of refrigeration is equal to 3.516853e-9 terawatts, you can use this simple formula to convert:

terawatts = tons of refrigeration × 3.516853e-9

The power in terawatts is equal to the power in tons of refrigeration multiplied by 3.516853e-9.

For example, here's how to convert 5 tons of refrigeration to terawatts using the formula above.

terawatts = (5 TR × 3.516853e-9) = 0.000000018 TW

How Many Terawatts Are in a Ton of Refrigeration?

There are 3.516853e-9 terawatts in a ton of refrigeration, which is why we use this value in the formula above.

1 TR = 3.516853e-9 TW|1 TW = 284,345,136.0939925 TR

Our ton of refrigeration to terawatt calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Tons of Refrigeration and terawatts are both units used to measure power. Keep reading to learn more about each unit.

What Is a Ton of Refrigeration?

A ton of refrigeration is a unit of power equal to 3,516.8528421 watts (W), the base unit for power. HVAC cooling capacity equal to 12,000 BTU/hr or 3.51685 kW. [1]

The ton of refrigeration is classified as a US customary unit of power. Tons of Refrigeration can be abbreviated as TR; for example, 1 ton of refrigeration can be written as 1 TR.

When working with tons of refrigeration (TR) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, tons of refrigeration (TR) are widely used across large-scale industrial, bulk, and macro-level power specifications within US customary workflows, engineering documentation, and technical data sheets.

What Is a Terawatt?

A terawatt is a unit of power equal to 1e+12 watts (W), the base unit for power. Equal to 10¹² Watts (1,000 GW). [2]

The terawatt is classified as an International System of Units (SI) unit of power. Terawatts can be abbreviated as TW; for example, 1 terawatt can be written as 1 TW.

In the metric system, "tera" is the standard SI prefix for trillions, or 10¹². This makes the terawatt (TW) a convenient decimal multiple of the watt (W).

In practice, terawatts (TW) are widely used across large-scale industrial, bulk, and macro-level power specifications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
