Cooking Measurement Converter — tsp, tbsp, cup, ml, oz, lb
~30 seconds
Enter an amount and pick the units to convert between. Volume converts to volume (tsp, tbsp, cups, ml, litres) and weight converts to weight (oz, lb, g, kg) using exact defined factors. Volume and weight cannot be converted generically — that depends on the ingredient.
What this calculator determines
It converts an amount between units within one dimension — volume to volume or weight to weight — using exact defined conversion factors.

1 lb
Assumptions & Conventions
- Same-dimension only
- Volume converts to volume and weight to weight; cross-dimension volume-to-weight conversion is rejected because it depends on ingredient density.
- US customary cup basis
- Volume units use the US customary cup convention (1 cup = 236.59 ml).
- Exact defined factors
- Within a dimension the factors are exact defined relationships, such as 1 tbsp = 3 tsp and 1 oz = 28.3495 g.
