A furnace delivers 8.0 × 104 btu per hour. how many kilocalories per hour is this?
vazorg [7]
For this case the first thing you should know is the following unit conversion.
 1 BTU = 0.25 Kilocalories
 We then have the following numerical value:
 8.0 * 10 ^ 4 \frac{BTU}{h}
 Applying the conversion of units we have:
 8.0 * 10 ^ 4 \frac{BTU}{h} * 0.25 \frac{Kcal}{BTU}
 Canceling units we have:
 20000 \frac{Kcal}{h}
 Answer:
 
This is 20000 kilocalories per hour
 
20000 \frac{Kcal}{h}
