Understanding the Units
What is a Fluid Ounce?
The US fluid ounce (29.574 ml) and the UK fluid ounce (28.413 ml) are different sizes. The UK version is about 4% smaller. This means a UK recipe calling for 8 fl oz gives you 227 ml, while 8 US fl oz gives you 237 ml. The difference is small per ounce but adds up in larger quantities.
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
