Formula and Step-by-Step

teaspoons × 4.58g/tsp = grams
  1. Start with 18 teaspoons of brown sugar
  2. 1 teaspoon of brown sugar = 4.58g
  3. 18 × 4.58 = 82.5g

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

Measuring Tip

If your brown sugar has hardened, microwave it with a damp paper towel for 20 seconds. Hard brown sugar is still the same weight but impossible to measure by volume.

Understanding the Units

What is a Teaspoon?

In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.

What is a Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 82.50 g, based on brown sugar having a density of 220g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 4.58 (grams per teaspoon for brown sugar). For 18 teaspoons: 18 × 4.58 = 82.50 g.
For the most accurate results, weigh brown sugar on a kitchen scale. If measuring by volume, pack it firmly into the measuring spoon and level it off. This conversion assumes packed brown sugar, which is the standard method.
Brown sugar should be firmly packed into the measuring spoon. This is the standard method and what this conversion assumes. Loosely measured brown sugar will weigh significantly less.
Reverse the conversion: 82.50 g ÷ 4.58 = 18 teaspoons. Or use the Grams to Teaspoons converter.
