Teaspoons to Grams Converter

Teaspoons measure volume, while grams measure mass, so there is no single universal number that converts every teaspoon to grams. The correct result depends on the density of the ingredient being measured. A teaspoon of water weighs about 4.92892 grams because a US teaspoon contains 4.92892 milliliters and water has a density close to one gram per milliliter. Flour, sugar, butter, and salt pack differently and therefore produce different weights in the same spoon volume. This converter uses practical kitchen factors for five common ingredients. One level teaspoon is treated as 4.92892 grams of water, 2.6 grams of all-purpose flour, 4.2 grams of granulated sugar, 4.73 grams of butter, or 6 grams of table salt. Multiply the number of teaspoons by the selected ingredient factor to obtain the estimated mass. For example, three teaspoons of granulated sugar weigh approximately 12.6 grams, while three teaspoons of flour weigh approximately 7.8 grams. Ingredient weights can vary in real kitchens. Flour becomes heavier when scooped directly from a bag or compressed into the spoon, whereas flour that is stirred, spooned gently, and leveled is lighter. Crystal size and moisture affect sugar and salt. Butter may leave air gaps unless softened and packed evenly. Brands, humidity, temperature, and the exact teaspoon standard can all introduce small differences, so recipe conversion tables often disagree by a few tenths of a gram. For casual cooking, the estimates are usually more precise than judging an unmarked spoon. For baking, candy making, nutrition tracking, or scaling a commercial recipe, use a digital kitchen scale whenever possible. Place the bowl on the scale, tare it to zero, and add the ingredient directly in grams. This avoids density assumptions and reduces variation between batches. The calculator uses the US teaspoon volume. A metric teaspoon is exactly 5 milliliters and can produce a slightly larger weight, so check which standard a recipe follows. Select the ingredient that most closely matches your recipe, enter the number of level teaspoons, and convert. If your ingredient is not listed, use its density in grams per milliliter multiplied by 4.92892, then multiply that grams-per-teaspoon value by the number of teaspoons.
