What does megajoule per second (MJ/s) measure?

Megajoule per second (MJ/s) is a power unit indicating energy transfer of one million joules every second, equivalent to one megawatt.

Why is ton (refrigeration) used in cooling systems?

Ton (refrigeration) expresses the cooling capacity required to melt a short ton of ice in 24 hours and is commonly utilized to rate HVAC and refrigeration equipment.

Can I use this conversion for dynamic cooling loads?

This conversion is designed for steady-state conditions and may not accurately reflect dynamic or varying cooling requirements.

What Is This Tool?

This converter transforms values from megajoule per second (MJ/s), a unit of power representing one million joules per second, to ton (refrigeration), which measures the cooling capacity equivalent to melting one short ton of ice in 24 hours. It is useful for translating power production or energy transfer rates into practical cooling unit quantities.

How to Use This Tool?

Enter the value in megajoule/second (MJ/s) that you want to convert.
Select 'megajoule/second [MJ/s]' as the input unit and 'ton (refrigeration)' as the output unit.
Click the convert button to see the equivalent value in ton (refrigeration).
Use the converted value for HVAC sizing, cooling capacity estimations, or power-to-cooling comparisons.

Key Features

Supports conversion between megajoule/second (MJ/s) and ton (refrigeration) units of power.
Based on a conversion rate where 1 MJ/s equals approximately 284.345 ton (refrigeration).
Browser-based unit conversion that requires no software installation.
Simple user interface for quick input and output of values.
Useful for power generation, HVAC, refrigeration, and building engineering calculations.

Examples

1 MJ/s converts to approximately 284.35 ton (refrigeration).
0.5 MJ/s converts to about 142.17 ton (refrigeration).

Common Use Cases

Expressing electrical or thermal power output from power plants or industrial turbines in cooling capacity terms.
Determining cooling loads for residential and commercial HVAC systems using tons of refrigeration.
Sizing cold-room refrigeration units and commercial refrigeration equipment.
Performing HVAC load calculations in building engineering and industrial processes.

Tips & Best Practices

Ensure input values represent steady-state power to match the conversion assumptions based on ice melting rates.
Use the conversion for planning and sizing HVAC and refrigeration equipment with respect to power ratings.
Double-check unit selections before converting to avoid errors between different power units.
Recognize that ton (refrigeration) is a non-SI unit and consider standard definitions in your region.

Limitations

Ton (refrigeration) is a non-SI measurement and may slightly differ depending on the exact definition used.
The conversion assumes steady heat removal equivalent to melting ice over 24 hours and may not apply to fluctuating or transient cooling loads.
Results should be used as estimation aids rather than precise scientific calculations.
