Question

A furnace delivers 8.0 × 104 btu per hour. how many kilocalories per hour is this?

Answer 1

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 (BTU)/(h)`
Applying the conversion of units we have:

`8.0 * 10 ^ 4 (BTU)/(h) * 0.25 (Kcal)/(BTU)`
Canceling units we have:

`20000 (Kcal)/(h)`
Answer:
This is 20000 kilocalories per hour

`20000 (Kcal)/(h)`
