About this converter

Dried kelp blocks smelt 20 items and blaze rods smelt 12 items. Coal and charcoal each smelt 8 items. Logs and planks each smelt 1.5 items. Sticks smelt 0.5 items and bamboo smelts 0.25 items.

How to use it
Pick two entries and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try 1 lava bucket against coal to plan a large smelt. The base unit is items smelted, so the math shows how many units each fuel replaces.
Values below are items smelted per single fuel in Java Edition. Burn ticks and seconds sit in each entry note. Blast furnaces and smokers run twice as fast but use the same fuel per item, so figures still hold. Figures track the Minecraft Wiki Smelting fuel table sourced to Java Edition game code with checks against Mojang patch notes. Bedrock matches for rows shown except where noted. Scaffolding is 0.25 after the 1.19 fix.
