A few clear measurement choices make a conversion much easier to use.
Fluid ounces vs. ounces
Decide whether your recipe is asking for volume or weight, then choose the appropriate tool.
Which cup size?
Understand the separate US customary, metric, Imperial, and food-label settings.
How to measure flour
Keep the recipe’s flour type, measurement method, and weight assumption together.
Put the guidance to work
Use the conversion tools when you know the units. Use an ingredient guide when you need to connect a food portion to its weight.
