If you think it's bad for water- try flour!
Agreed 100%- weigh everything. Even if your scales are wrong, everything will be measured wrong to the same degree, so the error will not matter.

I used to be a baker and it would amaze me when I saw US recipes measuring EVERYTHING in cups. That's measuring powders. By volume. The difference between the density at top and bottom of a bag of flour is around 30%. Mental yankee bastards

plus they never seem to agree on how bg a cup is.

Well, as standard a cup should be 250ml...
..But several books disagree :(

Again, weighing ftw!

I us cup = 8 fl oz
1/2 of a US pint, which is 16 fl oz.

(Ours is 20. This difference is also why US cars seem to get even crappier gas mileage than they really do - their gallon only 80% as big as ours.)

Same Error?
Depends is the error in your scales linear or not? Shifting the zero point by say 10g makes a bigger error in weighing 100g than 1000g and will screw up your bread :-)

Now what happens if the spring in your scales (old school) or the magic electrical pixies (modern) is not providing a linear response across its whole weighing range?

Would sir be interested in some calibration weights? (Apologies for pedantry)
