What is 100 Grams in Teaspoons?

On average, 100 grams ≈ 20.28 teaspoons
(100 grams of water = exactly 20.28 US teaspoons)

Water

100g = 20.28 tsp

All-Purpose Flour

100g = 38.46 tsp

Granulated Sugar

100g = 23.92 tsp

Table Salt

100g = 17.57 tsp

Butter

100g = 20.24 tsp

Vegetable Oil

100g = 22.17 tsp
Quick tip: Teaspoons are ideal for small amounts (100g typically lands between a fraction of a teaspoon and a couple of teaspoons, depending on the ingredient). For baking precision, a kitchen scale is always preferred over volume measures.

How to Convert 100 Grams to Teaspoons

Step 1: Understand Why the Answer Depends on the Ingredient

Grams measure mass; teaspoons measure volume. To turn 100 grams into teaspoons, you need the ingredient’s density — specifically, how many grams fit in one teaspoon (g/tsp). The simple formula is:

Teaspoons = 100 ÷ (grams per teaspoon)

Where the divisor changes per ingredient. Notice there is no “×3” in this equation — that multiplier only applies when converting to tablespoons, which are three times larger than teaspoons.

Key insight: For any ingredient, the 100-gram-to-teaspoon answer is simply 100 times the 1-gram-to-teaspoon answer. So once you know the per-gram value, scaling is trivial.

Step 2: Try It with Water (the Baseline)

Water has a density of 1 g/mL, and one US teaspoon holds about 4.93 mL of water. Therefore:

Teaspoons of water = 100 ÷ 4.93 = 20.28 tsp

So 100 grams of water equals approximately 20.28 US teaspoons (20 2/7 when expressed as a fraction).

Step 3: Worked Example for Flour

Goal: Convert 100 grams of all-purpose flour to teaspoons

1. Look up the conversion factor for flour:

All-purpose flour ≈ 2.60 g/tsp

2. Apply the formula:

Teaspoons = 100 ÷ 2.60

3. The result:

≈ 38.46 teaspoons

Answer: 100 grams of all-purpose flour ≈ 38.46 tsp (38 6/13).

Step 4: Common-Ingredient Cheat Sheet for 100 Grams

  • Water / Milk: 100g ≈ 20.28 tsp (20 2/7)
  • All-purpose flour: 100g ≈ 38.46 tsp (38 6/13)
  • Granulated sugar: 100g ≈ 23.92 tsp (23 12/13)
  • Brown sugar: 100g ≈ 21.98 tsp (21 31/32)
  • Butter: 100g ≈ 20.24 tsp (20 7/29)
  • Table salt: 100g ≈ 17.57 tsp (17 15/26)
  • Honey: 100g ≈ 14.12 tsp (14 1/8)
  • Baking powder: 100g ≈ 43.86 tsp (43 25/29)
  • Baking soda: 100g ≈ 44.44 tsp (44 4/9)
  • Cocoa powder: 100g ≈ 46.51 tsp (46 16/31)

Reminder: These figures assume a US/metric teaspoon (4.93–5 mL). The traditional UK imperial teaspoon (5.92 mL) yields slightly different numbers — always match the teaspoon standard used in your recipe.

Rounding rules used on this page: Decimal teaspoons are rounded to two places; fractions are expressed in 32nds or simpler equivalents (¼, ⅓, ½, ⅔, ¾) for practical kitchen use.

Grams & Teaspoons: A Quick Primer

The Gram — Mass, Not Volume

A gram (g) is the base unit of mass in the metric system; one gram equals one-thousandth of a kilogram. Because grams measure how heavy something is — not how much space it takes up — they deliver consistent results regardless of how an ingredient is packed, sifted, or scooped. That precision is exactly why professional bakers favor grams for flour, sugar, and leavening agents like the 100 grams you might see in a recipe.

The Teaspoon — Volume in a Familiar Form

A teaspoon (tsp) is one of the smallest practical volume measures in everyday cooking. It is exactly one-third of a tablespoon and is the unit most often used for spices, extracts, baking powder, and salt — the kinds of ingredients where 100 grams often falls. The catch: a “teaspoon” doesn’t mean the exact same thing everywhere in the world.

US Teaspoon

≈ 4.93 mL (1/6 US fluid ounce). The default in American recipes and nutrition labels.

Metric Teaspoon

Exactly 5 mL. Used across Europe, Canada, Australia, and most metric-system countries.

UK Imperial Teaspoon

≈ 5.92 mL (traditional). Modern British recipes typically use the 5 mL metric teaspoon instead.

Australian Teaspoon

5 mL (metric standard). Note: Australia’s tablespoon is 20 mL — but the teaspoon stays at 5 mL.

FAQ: 100 Grams to Teaspoons

❓ How many teaspoons is 100 grams?

It depends on the ingredient’s density. Common approximations for 100 grams:
  • Water: 100 g ≈ 20.28 tsp
  • All-purpose flour: 100 g ≈ 38.46 tsp
  • Granulated sugar: 100 g ≈ 23.92 tsp
  • Butter: 100 g ≈ 20.24 tsp
  • Table salt: 100 g ≈ 17.57 tsp
For precise results, always check the ingredient-specific value rather than assuming “1 gram = 1 teaspoon.”

⚖️ Why do 100-gram-to-teaspoon answers change by ingredient?

Because grams measure weight while teaspoons measure volume. Two ingredients with the same weight can occupy very different volumes. 100 grams of honey is dense and compact, so it fills only a small fraction of the space 100 grams of light, airy flour would occupy.

📏 What’s the formula to convert 100 grams to teaspoons?

The formula is:
Teaspoons = Grams ÷ (grams per teaspoon)
For 100 grams of water (4.93 g/tsp):
100 ÷ 4.93 = 20.28 teaspoons.
Substitute the right “grams per teaspoon” value for whichever ingredient you’re using.

🥄 Is a US teaspoon the same as a metric teaspoon?

Almost. A US teaspoon is 4.93 mL; a metric teaspoon (used in the UK today, Australia, Canada, and most of Europe) is exactly 5 mL. The difference is small enough that most recipes treat them interchangeably. The older UK imperial teaspoon (5.92 mL) is the outlier — if you’re using a vintage British recipe, the 100-gram answer in teaspoons may run slightly lower than a modern conversion.

🎯 What’s the most accurate way to measure 100 grams for a recipe?

Use a digital kitchen scale. Volume conversions are estimates because flour can be sifted or packed, sugar can clump, and herbs settle differently every time. A scale removes all of that variance and gives you exactly 100 grams every time.
Pro tip: If you don’t own a scale, level off the teaspoon with the flat edge of a knife for the closest match to the values shown on this page.
