Formula and Step-by-Step

cups × 120g/cup ÷ 453.592g/lb = pounds
  1. Start with 3 cups of self-rising flour
  2. 1 cup of self-rising flour = 120g
  3. 3 × 120 = 360g
  4. Convert grams to pounds: 360 ÷ 453.592 = 0.79 lb

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

For the most consistent results, weigh self-rising flour on a kitchen scale. Volume measurements can vary by 20-30% depending on how the flour is scooped.

Understanding the Units

What is a Cup?

There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.

What is a Pound?

Pounds are the standard weight unit for buying ingredients in the US. A standard bag of flour is 5 pounds (2,268g) and a standard bag of sugar is 4 pounds (1,814g).

Frequently Asked Questions

About 0.79 lb, based on self-rising flour having a density of 120g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 120 (grams per cup for self-rising flour), then divide by 453.592 to convert grams to pounds. For 3 cups: 3 × 120 = 360g, then 360 ÷ 453.592 = 0.79 lb.
For the most accurate results, weigh self-rising flour on a kitchen scale. If measuring by volume, sift or whisk first to break up clumps, then spoon into the measuring cup and level off. Do not scoop directly from the bag.
Yes, quite a bit. If you spoon the flour into your measuring cup and level it off, you will get about 120 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 132 to 150 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 0.79 lb × 453.592 = 360g, then 360g ÷ 120 = 3 cups. Or use the Pounds to Cups converter.
