Enter the burn rate of the firewood, the number of hours you burn per day, and the number of days you plan to use the firewood to calculate the total firewood usage.

Firewood Usage Formula

The formula to calculate the total firewood usage is:

FU = BR * H * D

Variables:

  • FU is the total firewood usage (cubic feet)
  • BR is the burn rate (cubic feet per hour)
  • H is the number of hours of burning per day
  • D is the number of days of usage

To calculate the total firewood usage, multiply the burn rate by the number of hours burned per day and then by the number of days of usage.

What is Firewood Usage?

Firewood usage is the amount of firewood consumed over a period of time. It is an important measure for those who rely on wood as a primary or secondary source of heat. Understanding firewood usage helps in planning and ensuring a sufficient supply of wood throughout the burning season.

How to Calculate Firewood Usage?

The following steps outline how to calculate the total firewood usage:


  1. Determine the burn rate (BR) of the firewood in cubic feet per hour.
  2. Identify the number of hours (H) you burn firewood each day.
  3. Count the number of days (D) you plan to use the firewood.
  4. Use the formula FU = BR * H * D to calculate the total firewood usage (FU).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Burn rate (BR) = 0.5 cubic feet per hour

Hours of burning per day (H) = 5 hours

Days of usage (D) = 30 days
