Formula and Step-by-Step

cups × 128g/cup ÷ 453.592g/lb = pounds
  1. Start with 1.49 cups of cornstarch
  2. 1 cup of cornstarch = 128g
  3. 1.49 × 128 = 190.72g
  4. Convert grams to pounds: 190.72 ÷ 453.592 = 0.42 lb

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

Measuring Tip

Different flour types have very different weights per cup. Always check the specific flour your recipe calls for rather than using a generic "flour" conversion.

Frequently Asked Questions

About 0.42 lb, based on cornstarch having a density of 128g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 128 (grams per cup for cornstarch), then divide by 453.592 to convert grams to pounds. For 1.49 cups: 1.49 × 128 = 190.72g, then 190.72 ÷ 453.592 = 0.42 lb.
For the most accurate results, weigh cornstarch 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 128 grams per cup. If you dip directly into the flour bag and sweep level, the flour packs tighter and you can end up with 140.8 to 160 grams per cup instead. This conversion uses the spoon-and-level method, which is the standard most baking references follow.
Reverse the conversion: 0.42 lb × 453.592 = 190.72g, then 190.72g ÷ 128 = 1.49 cups. Or use the Pounds to Cups converter.
