How Do I Convert kg/h of Steam to ton/h?

To convert a steam flow rate from kilograms per hour (kg/h) to metric tons per hour (t/h), divide the kg/h value by 1,000.

Steam flow (t/h) = Steam flow (kg/h) ÷ 1,000

For example:

5,000 kg/h ÷ 1,000 = 5 t/h

Therefore, a steam boiler producing 5,000 kg of steam per hour has a steam capacity of 5 metric tons per hour.

kg/h to ton/h Steam Conversion Table

The conversion is linear because 1 metric ton = 1,000 kg. The U.S. National Institute of Standards and Technology (NIST) also defines 1 metric ton (t) as 1,000 kilograms.

How Do I Convert ton/h Back to kg/h?

For the reverse conversion, multiply metric tons per hour by 1,000:

Steam flow (kg/h) = Steam flow (t/h) × 1,000

Example:

6 t/h × 1,000 = 6,000 kg/h

So a 6 t/h industrial steam boiler is rated to produce 6,000 kg/h of steam at its specified rated conditions.

Is 1 ton/h of Steam Always 1,000 kg/h?

Yes—if “ton” means a metric ton (tonne).

1 metric ton/hour = 1,000 kg/hour

However, the word “ton” can be ambiguous in international projects.

For industrial boiler specifications expressed as t/h, confirm that the supplier and buyer are both referring to metric tonnes per hour.

This is especially important for international RFQs, where “10 ton boiler” should not be used without clearly defining the unit.

Does Steam Pressure Change the kg/h to t/h Conversion?

No.

If you are converting only the mass flow rate, steam pressure and temperature do not change the basic conversion:

1,000 kg/h = 1 t/h

Pressure and temperature do matter when calculating steam enthalpy, thermal power, fuel consumption, pipe sizing and other engineering parameters, but they do not change the mass conversion between kg/h and metric t/h.

Is Boiler Capacity in t/h the Same as Steam Flow Rate?

For industrial steam boilers, rated capacity in t/h commonly describes the mass of steam the boiler is designed to generate per hour at specified operating conditions.

For example:

• 1 t/h = 1,000 kg/h
• 2 t/h = 2,000 kg/h
• 5 t/h = 5,000 kg/h
• 10 t/h = 10,000 kg/h
• 20 t/h = 20,000 kg/h

However, boiler selection should not be based on the converted number alone.

Actual boiler sizing should also consider:

• minimum steam demand;
• normal steam demand;
• peak steam demand;
• working pressure;
• steam temperature;
• fuel;
• operating hours;
• and expected future load.

Quick Answer

How do I convert kg/h of steam to ton/h?

Divide the steam flow in kg/h by 1,000:

t/h = kg/h ÷ 1,000

Therefore:

• 500 kg/h = 0.5 t/h
• 1,000 kg/h = 1 t/h
• 5,000 kg/h = 5 t/h
• 10,000 kg/h = 10 t/h
• 20,000 kg/h = 20 t/h

Always confirm that “ton” means metric ton (tonne) when preparing an international industrial boiler specification or quotation.
