Formula and Step-by-Step

  4. Convert grams to pounds: 340.6 ÷ 453.592 = 0.75 lb

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

Measuring Tip

Ripeness affects density. Riper fruit mashes more smoothly and packs more densely per cup than firmer fruit. Weigh for the most consistent results.
