Formula and Step-by-Step

(pounds × 453.59g/lb) ÷ 148g/cup = cups
  1. Start with 1.5 pounds of flaxseed
  2. Convert pounds to grams: 1.5 × 453.59 = 680.39g
  3. 1 cup of flaxseed = 148g
  4. 680.39g ÷ 148g/cup = 4.60 cups

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 flaxseed on a kitchen scale. Small seeds are easy to over-measure by volume.

Frequently Asked Questions

About 4.60 cups, based on flaxseed having a density of 148g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert pounds to grams (1 pound = 453.592g), then divide by 148 (grams per cup). For 1.5 pounds: 1.5 × 453.592 = 680.39g, then 680.39 ÷ 148 = 4.60 cups.
For the most accurate results, weigh flaxseed on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 4.60 cups × 148g/cup = 680.39g, then 680.39g ÷ 453.592 = 1.5 pounds. Or use the Cups to Pounds converter.
