How to Convert Energy Units From BTU to Pounds Per Hour for Steam
- 1). Convert the BTUs into hp units first. One unit of hp is equal to 33,472 BTUs. Thus, you will divide the BTUs by 33,472 to get your hp units.
For example, if your BTUs equal 7,363,840, then we'll divide that number by 33,472, giving us 220 hp units (7,363,840/33472 = 220). - 2). Convert your units of hp into pounds of steam per hour by multiplying the number calculated in the previous step by 34.5.
Using numbers from our previous example, if you multiply 220 by 34.5, then you get 7,590 pounds of steam per hour created by your boiler (220 x 34.5 = 7,590). - 3). Double-check your calculations using your calculator by doing the exact same calculations and making sure the answers are the same.
Or, you could reverse your math to verify your calculations. Start by dividing the pounds of steam per hour by 34.5, then multiply that number by 33,472. You should have your original BTU number that you started with.
Here is an example using the numbers from before:
7,590/34.5 = 220
220 x 33,472 = 7,363,840
If your numbers match up, then you've done your math correctly.
