Understanding the Units
What is a Fluid Ounce?
There are 8 fluid ounces in a US cup and 128 fluid ounces in a US gallon. The UK fluid ounce is slightly smaller (28.413 ml vs 29.574 ml), so UK and US recipes using fluid ounces will differ slightly.
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.
