A furnace is rated 4000 BTU per hour. How many foot pounds of energy are released in one hour?
Kipish [7]
To solve this we are going to use a conversion factor. We know that 1 BTU per hour is approximately 778 foot-pounds of energy per hour, so our conversion factor will be: \frac{778foot-pound}{1BTU}.

Now we just need to multiply <span>4000 BTU by our conversion factor:
</span>4000BTU*\frac{778foot-pound}{1BTU}=3112000foot-pound
<span>
We can conclude that the furnace released </span><span>3,112,000 foot pounds of energy in one hour.</span>
