Raw vs cooked oats (dry)
Weight depends on how much water you use. Cooked weight is about +150% of the raw weight, so 200 g raw becomes about 500 g.
Raw to cooked weight
Meat loses water, rice and pasta absorb it. Convert between raw and cooked weight so your portions and meal prep stay accurate.
What happens to oats (dry) when cooked
The cooked weight depends entirely on how much water you add, so porridge varies a lot.
Tips for accurate weights
- Thicker porridge weighs less than a thin one.
- Weigh the dry oats and note the water you used.
