How the Campfire Firewood Calculator works
Dry hardwood burns at roughly 1.5 kg per hour for a small cooking fire, 3 kg for a medium camp fire, and 6 kg for a large bonfire. Firewood = hours × nights × burn rate. Bundles = firewood ÷ bundle weight, rounded up. Softwood and damp wood burn differently, so buy a little extra. Buy wood locally to avoid spreading pests, and check fire restrictions before you go. Example: with Fire time per night 3 h, Number of nights 2, and Fire size Medium camp fire, the result is Firewood needed (kg) = 18; Bundles to buy = 6; Firewood per night (kg) = 9.
