Calculate firewood volume, cords, face cords, cubic feet, stack size, estimated weight, heat value, and total firewood cost. Use this firewood calculator for wood piles, stacked firewood, delivery orders, heating estimates, and comparing firewood prices.
Stack size method:
The calculator multiplies stack length by height by depth to estimate cubic feet, then divides by 128 to convert to full cords.
Known cords method:
Enter a known amount in full cords, face cords, cubic feet, or cubic meters to convert into other firewood units.
Cost estimate:
The calculator multiplies full cords by price per cord, then adds delivery and stacking fees.
Heat estimate:
The calculator multiplies cords by estimated million BTU per cord and adjusts for moisture or seasoning.
A firewood calculator helps estimate whether a stack, delivery, or order is close to the amount of wood you expect.
It can be useful for buying firewood, comparing cord prices, estimating winter heating supply, planning storage space, and checking stacked wood volume.
Your result shows full cords, face cords, cubic feet, cubic meters, estimated weight, heat value, total firewood cost, cost per cord, cost per million BTU, and delivery or stacking charges. These are estimates based on stack size, wood type, moisture level, and prices entered.
A full cord of stacked firewood is 128 cubic feet, commonly measured as 4 feet high by 4 feet deep by 8 feet long.
A face cord is usually one stack that is 4 feet high and 8 feet long, with depth equal to the log length. If the logs are 16 inches long, a face cord is about one-third of a full cord.
Multiply stack length by height by depth in feet to get cubic feet, then divide by 128 to estimate full cords.
Different species have different heat values. Dense hardwoods like oak and hickory usually produce more heat per cord than softwoods like pine.
