Unit Conversions
Recipes can use different units than the resource’s base unit. OpenBook handles conversions automatically:| If Recipe Uses | And Resource Uses | OpenBook Will |
|---|---|---|
| 18g | g (Grams) | Deduct 18g directly |
| 0.5kg | g (Grams) | Convert to 500g, then deduct |
| 150ml | ml (Milliliters) | Deduct 150ml directly |
| 0.15l | ml (Milliliters) | Convert to 150ml, then deduct |
