kW To MBH Calculator: Convert Kilowatts To MBH (+ Chart)

If you need to calculate MBH from kW, you can use our kW to MBH calculator or consult the conversion chart. Basically, we are converting 2 units we in HVAC use to denote heating/cooling capacity (kW stands for kilowatts and MBH stands for 1000s BTU/hr).

Here is the online calculator you can use to make this conversion, followed by the formula and 0.01-50 kW to MBH conversion chart:

Let’s say you want to convert 8 kW to MBH. You just insert ‘8’ in the kW input field, hit ‘Calculate’, and you get this result (screenshot):

You can immediately see that 8 kW is equal to 27.30 MBH (that’s 27,300 BTU/h). By the way, if you need this conversion in reverse – MBH to kW – you can check a similar MBH to kW calculator here.

Here’s how this conversion works:

kW To MBH Formula

To denote cooling/heating capacity, we use different units. In the US, we might use MBH or thousands of BTU/h (British Thermal Units per hour). In Europe, Asia, and most of the world, we use kW or kilowatts. We can convert between these two units using this simple rule:

1 kW = 3.412 MBH

This simply means that 1 kW is equal to 3.412 MBH. Once we know this relationship, we can write the following kW to MBH formula:

MBH = kW × 3.412

This equation tells us that we need to multiply kW by 3.412 to get MBH.

Quick Example: How many MBH is 5 kW? Simply insert 5 kW in the equation above like this to get the result:

MBH (5 kW) = 5 kW × 3.412 = 17.06 MBH

We quickly calculate that 5 kW is equal to 17.06 MBH.

To avoid manual calculation, you can use the calculator above, or just consult this conversion chart:
