Factorio Fuel Value Comparison (Energy MJ)

Which Factorio fuel is best? Compare 10 fuel energy values, from thruster fluid 0.05 MJ to fusion cell 40000 MJ. Official wiki data. All burner values ranked.

Visual comparison

Log scale: values span 800,000x from smallest to largest, so bar lengths are logarithmic. Labels and table show exact values.

About this converter

Factorio fuels span six orders of magnitude in one table. Thruster fuel and oxidizer sit at 0.05 MJ each for space platforms. Wood and carbon sit at 2 MJ, coal at 4, solid fuel at 12 and rocket fuel at 100. Nuclear fuel jumps to 1210 MJ per item for burner devices. Reactor fuels top the table with uranium cells at 8000 MJ and fusion cells at 40000 MJ. One fusion cell matches 20000 wood. Every figure here is the official wiki prototype value.

How to use it

Pick two fuels and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try 1 uranium cell against coal to see the 8000 versus 4 gap in MJ or GJ.

Values are per item energy content from game prototypes, not per stack or per rocket. Carbon, fusion cells and thruster fluids come from the Space Age expansion and stay flagged. Vehicle speed and acceleration bonuses ride in notes where they sharpen a row. Burner devices cannot burn uranium or fusion cells, which only reactors accept. Stack energy totals ride in notes: wood stacks to 200 MJ while uranium cells stack to 400 GJ.

FAQ

What is the weakest fuel?

Wood at 2 MJ per item. Coal doubles it at 4 MJ.

What is the strongest fuel?

Fusion power cell at 40 GJ, five times a uranium cell at 8 GJ. Both run reactors only, never burner devices.

How much is rocket fuel?

100 MJ, between solid fuel at 12 and nuclear fuel at 1210. It also grants 180 percent vehicle acceleration.

Are these per stack?

No. Values are per item. Stack totals ride in notes: wood stacks to 200 MJ and uranium cells to 400 GJ per stack of 50.
