Sulfuric acid — Factorio Production Calculator
Sulfuric acid is crafted in the chemical plant in 1 seconds, producing 50 per craft from 5 × Sulfur, 1 × Iron plate, 100 × Water. At 60 per minute you need 0.02 chemical plants, and the chain behind it draws on 3 raw resources: water, petroleum gas, iron ore.
Production chain for 60 Sulfuric acid / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Sulfuric acid | 60 | 0.02 | Chemical plant |
| Sulfur | 6 | 0.05 | Chemical plant |
| Iron plate | 1.2 | 0.06 | Furnace |
Raw materials
| Resource | Per minute |
|---|---|
| Water | 210 |
| Petroleum gas | 90 |
| Iron ore | 1.2 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Sulfuric acid recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Chemical plant | 1 s | 50 | Sulfur × 5, Iron plate × 1, Water × 100 |
What the whole chain needs
60 sulfuric acids per minute pulls in 2 intermediate products, and the whole tree comes to 0 machines across 2 machine types, fed by 3 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 210 per minute, which is 0.23 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses sulfuric acid
2 base-game recipes consume sulfuric acid, sorted by how much each one takes:
- Battery — 20 per craft
- Processing unit — 5 per craft
What sulfuric acid is made from
- Sulfur — 5 per craft
- Iron plate — 1 per craft
FAQ
How many chemical plants do I need for 60 sulfuric acids per minute?
0.02 chemical plants. One at standard speed produces 3,000 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does sulfuric acid take?
At 60/min the chain consumes 210 water per minute, 90 petroleum gas per minute, 1.2 iron ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is sulfuric acid needed for science packs?
Not directly. It feeds Battery and Processing unit, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
