BTU/h To MBH Calculator: Convert BTU/h To MBH (+ Chart)

It’s quite easy to convert BTU/h to MBH. Basically, we are converting British Thermal Units per hour (BTH/h) to a thousand British Thermal Units per hour (MBH or 1000 BTU/h). For the fastest BTU/h to MBH conversion, we prepared a calculator (insert BTH/h, get MBH), along with the 1-200,000 BTU/hr to MBH conversion chart.

Example: How many MBH is 20,000 BTU/h? Simple. You insert 20,000 BTU/h in the calculator below, hit ‘Calculate’, and you get the result immediately: 20,000 BTU/h is equal to 20 MBH.

Here is this calculator:

This online is very simple to use. You can try converting 9,000 BTU/h to MBH. Just insert ‘9,000’ in the BTH/h input field, hit ‘Calculate’, and you get the result in this form:

You can see right away that 9000 BTU/h is equivalent to 9 MBH. You can also see a similar MBH to BTU/h calculator here (does this conversion in reverse).

Honestly, you can do this conversion on the go in your head. Here is how simple the math is:

BTU/h To MBH Formula

In HVAC, we use both of these units to denote heating or cooling capacity. The basic unit we use is BTU/h but sometimes we also use MBH. MBH stands for thousand BTU/h (that ‘M’ in MBH stands for ‘thousand’, it’s a Roman numeral M). Here is the simplest way of looking at this conversion:

1 MBH = 1000 BTU/h

Now, if we want to convert BTU/h to MBH, we can rearrange this a bit to get the general formula:

MBH = BTU/h / 1000

Basically, we need to divide BTU/h by a factor of 1000 to get the MBHs.

Quick Example: How many MBH is 72,000 BTU/h? Let’s insert these BTU/h in the equation above like this:

MBH (72,000 BTU/h) = 72,000 BTU/h / 1000 = 72 MBH

We see that 72,000 BTU/h is equal to 72 MBH. Here is the full conversion chart you can always use for the quickest conversion:
