How Much Is 18 Teaspoons of Olive Oil in Grams?

18 teaspoons of olive oil weighs 81.00 g. This is based on olive oil having a density of 216g per cup. Because teaspoons measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 18 teaspoons.

Formula and Step-by-Step

teaspoons × 4.5g/tsp = grams
  1. Start with 18 teaspoons of olive oil
  2. 1 teaspoon of olive oil = 4.5g
  3. 18 × 4.5 = 81g

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

Measuring Tip

Oils are lighter than water, so the same volume weighs less. Pour slowly into the measuring spoon for accuracy, and wipe any drips from the outside before reading.

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 81.00 g, based on olive oil having a density of 216g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 4.5 (grams per teaspoon for olive oil). For 18 teaspoons: 18 × 4.5 = 81.00 g.
For the most accurate results, weigh olive oil 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 olive oil 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: 81.00 g ÷ 4.5 = 18 teaspoons. Or use the Grams to Teaspoons converter.
