Formula and Step-by-Step

teaspoons × 5.08g/tsp = grams
  1. Start with 18 teaspoons of milk
  2. 1 teaspoon of milk = 5.08g
  3. 18 × 5.08 = 91.5g

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 spoon 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 Teaspoon?

One teaspoon holds about 5 milliliters. There are 3 teaspoons in a tablespoon and 48 teaspoons in a cup. Teaspoon accuracy matters most with leaveners like baking powder and baking soda, where small differences affect rise and texture.

What is a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

Frequently Asked Questions

About 91.50 g, based on milk having a density of 244g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 5.08 (grams per teaspoon for milk). For 18 teaspoons: 18 × 5.08 = 91.50 g.
For the most accurate results, weigh milk on a kitchen scale. If measuring by volume, use a liquid measuring spoon on a flat surface and read the level at eye height.
Temperature has a minimal effect on most cooking liquids. The density of milk 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: 91.50 g ÷ 5.08 = 18 teaspoons. Or use the Grams to Teaspoons converter.
