  1. Start with 40 fluid ounces of corn syrup
  2. 1 fluid ounce of corn syrup = 41g
  3. 40 × 41 = 1,640g
  4. Convert grams to ounces: 1,640 ÷ 28.3495 = 57.85 oz

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

Measuring Tip

For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.

Frequently Asked Questions

About 57.85 oz, based on corn syrup having a density of 328g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of fluid ounces by 41 (grams per fluid ounce for corn syrup), then divide by 28.3495 to convert grams to ounces. For 40 fluid ounces: 40 × 41 = 1,640g, then 1,640 ÷ 28.3495 = 57.85 oz.
Weighing corn syrup on a kitchen scale is strongly recommended. It is thick and sticky, so it clings to measuring vessels. If you must measure by volume, lightly oil the measuring cup first so it slides out cleanly.
Temperature has a minimal effect on most cooking liquids. The density of corn syrup changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
Reverse the conversion: 57.85 oz × 28.3495 = 1,640g, then 1,640g ÷ 41 = 40 fluid ounces. Or use the Ounces to Fluid Ounces converter.
