Acreage & Fuel Load Tool
Estimate how much fuel a burn unit holds, how much will be consumed, and the rough PM2.5 smoke emissions.
Fuel estimate — Grass / light fuels
- Burn area
- 5 acres
- Fuel loading
- 1.5 tons/acre
- Total available fuel
- 7.5 tons
- Fuel consumed (90%)
- 6.75 tons
Estimated PM2.5 smoke emissions
114.75lb
≈ EPA AP-42 factor of 17 lb PM2.5 per ton consumed. Higher emissions mean a smoke management plan is more likely required.
Planning estimate only
This calculator is a planning aid, not a regulatory standard or a substitute for trained judgment. Always follow your state and local burn regulations, obtain required permits, check for active burn bans, and consult a certified burn manager for real burns.
