1 teaspoon = 5ml
1 cup = 240ml
1 ricebowl = 375ml
1 small can (Campbell's soup 310g) = 310ml (approx)
1 big can (Heinz baked beans 420g) = 420ml (approx)
Eggs: The eggs I use are approx. 50g in weight (Size 5 / small)
g vs ml: The density of water is 1 g/ml under normal conditions, so for water, 1g = 1ml. I use the same conversion as a rough gauge for rice and mixed vege after weighing and measuring them.
