Measuring Mimosa

[Methodology]

Hi, I was just wondering if anyone has any general methods of measuring mimosa (i.e. roughly 100g/half cup?), I don't have a scale, and it seems wasteful to go buy one just for this, I was going to order a mg scale, which is way more useful in the end. How would I go about weighing it with just standard measuring cups?

Better go buy a scale, it is always useful to have one around, maybe you'll find it useful in cooking/pastry?
