A question about fast fibre amounts

[Supertrooper]

Does anyone know how much fast fibre a normal round scoop holds? Kg wise? thanks in advance xx

I think that a normal stubbs scoop is approx 1.5kg...but Im not 100%.... kitchen scales are the best way on this I think!! x

Not sure, all I know is it expands greatly I use kitchen scales also to measure
