Formula and Step-by-Step

pints × 490g/pt ÷ 28.3495g/oz = ounces
  1. Start with 18 pints of buttermilk
  2. 1 pint of buttermilk = 490g
  3. 18 × 490 = 8,820g
  4. Convert grams to ounces: 8,820 ÷ 28.3495 = 311.12 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.

Understanding the Units

What is a Pint?

The pint is one of the most confusing measurements across countries because the difference between US and UK versions is so large. Always check which country a recipe comes from before measuring in pints.

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

Frequently Asked Questions

About 311.12 oz, based on buttermilk having a density of 245g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of pints by 490 (grams per pint for buttermilk), then divide by 28.3495 to convert grams to ounces. For 18 pints: 18 × 490 = 8,820g, then 8,820 ÷ 28.3495 = 311.12 oz.
For the most accurate results, weigh buttermilk on a kitchen scale. If measuring by volume, use a liquid measuring cup on a flat surface and read the level at eye height.
Temperature has a minimal effect on most cooking liquids. The density of buttermilk changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
