Formula and Step-by-Step

teaspoons × 4.17g/tsp = grams
  1. Start with 4.5 teaspoons of granulated sugar
  2. 1 teaspoon of granulated sugar = 4.17g
  3. 4.5 × 4.17 = 18.75g

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

Measuring Tip

Sugar is one of the easier dry ingredients to measure by volume because the crystals pack relatively consistently compared to flour or cocoa powder.

Understanding the Units

What is a Teaspoon?

A teaspoon (tsp) is a US customary unit of volume equal to 4.929 milliliters or 1/3 of a tablespoon. It is the standard measure for spices, leaveners, extracts, and other small-quantity ingredients.

What is a Gram?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

Frequently Asked Questions

About 18.75 g, based on granulated sugar having a density of 200g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 4.17 (grams per teaspoon for granulated sugar). For 4.5 teaspoons: 4.5 × 4.17 = 18.75 g.
For the most accurate results, weigh granulated sugar on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon and level it off with a straight edge rather than scooping directly.
Granulated and powdered sugars should be spooned into the measuring spoon and leveled off. Do not pack them unless the recipe specifically says to.
Reverse the conversion: 18.75 g ÷ 4.17 = 4.5 teaspoons. Or use the Grams to Teaspoons converter.
