Can I convert litres to kilograms here?
Not directly — that depends on what you are measuring. Volume becomes mass only once you know the density. Water is the convenient case: one litre is almost exactly one kilogram. Oil, flour and alcohol are all lighter.

The US legal cup is 240 mL and the customary cup used in recipes is about 236.6 mL. The round 250 mL cup is the Australian and metric standard. In baking the gap is enough to notice.
