Grams To Drops
5 g of water is about 5 mL, which is roughly 100 drops from a standard dropper.
Quick answer: Turn grams into mL, then multiply by 20 drops per mL. For example, 5 g of water is 100 drops, 5 g of granulated sugar is 118.29 drops and 5 g of brown sugar (packed) is 111.07 drops.
The grams to drops formula
First turn grams into mL. Then multiply the mL by 20 drops.
A drop is not a fixed size, so the answer is an estimate.
Take 5 g of water. 5 × 236.588 ÷ 236.59 × 20 gives 100 drops.
Take 5 g of granulated sugar. 5 × 236.588 ÷ 200 × 20 gives 118.29 drops.
Grams and drops
A common rule says 20 drops make 1 mL, though the size of a drop depends on the dropper and the liquid (People’s Pharmacy: How Many Milliliters in One Drop).
So one drop of water is about 0.05 mL and weighs about 0.05 g.
How to convert grams to drops step by step
- Enter the amount in grams.
- Pick the ingredient, or enter its grams per cup.
- Read the result in Drops.
- Check it against the quick table.
Example 1: 5 g of water
- Start with 5 g of water.
- 5 × 236.588 ÷ 236.59 × 20 = 100.
- The amount is 100 drops.
5 g of water = 100 drops
Example 2: 5 g of granulated sugar
- Start with 5 g of granulated sugar.
- 5 × 236.588 ÷ 200 × 20 = 118.29.
- The amount is 118.29 drops.
5 g of granulated sugar = 118.29 drops
Example 3: 5 g of brown sugar (packed)
- Start with 5 g of brown sugar (packed).
- 5 × 236.588 ÷ 213 × 20 = 111.07.
- The amount is 111.07 drops.
5 g of brown sugar (packed) = 111.07 drops
Round only at the end. Weights per cup are good to about 5 percent, so treat the answer as a cooking guide and not as a lab value.

A quick mental shortcut for grams to drops
For water, multiply the grams by 20. So 2 g is about 40 drops.
Why drops vary
Thick liquids like honey form larger drops, and thin liquids like alcohol form smaller ones. The shape of the dropper tip also matters.
For doses of medicine, use the measuring device that comes with the product.
Why the ingredient changes the answer
One US cup of water weighs about 236.59 g, one cup of granulated sugar weighs about 200 g, and one cup of brown sugar (packed) weighs about 213 g.
So 5 g gives 100 drops for water, 118.29 drops for granulated sugar and 111.07 drops for brown sugar (packed).
Going the other way
Take 100 drops of water. Reverse the sum and you get 5 g.
If the round trip does not return your start value, one number was typed or rounded wrongly.
If your ingredient is not listed
Weigh one level US cup of it and use that number as the grams per cup. Chart weights vary by brand and by how the cup is filled.
Flour weights in published charts assume the scoop and level method (Baking Like a Chef: Cups to Grams Conversions).
The same amount for other ingredients
The page above uses water as its main ingredient. At the default amount of 5 g, it gives 100 drops.
At 5 g, granulated sugar gives 118 drops. At 5 g, brown sugar (packed) gives 111 drops. At 5 g, powdered sugar gives 197 drops.
At 5 g, all-purpose flour gives 189 drops. At 5 g, bread flour gives 186 drops. At 5 g, butter gives 104 drops.
At 5 g, table salt gives 81 drops. At 5 g, baking soda gives 103 drops. At 5 g, baking powder gives 123 drops.
At 5 g, cocoa powder gives 278 drops. At 5 g, honey gives 69.6 drops. At 5 g, milk gives 96.6 drops.
At 5 g, vegetable oil gives 109 drops. At 5 g, uncooked white rice gives 128 drops. At 5 g, rolled oats gives 263 drops.
The spread shows why one factor cannot serve every food. Pick your own ingredient from the list before you trust the answer.
Doubling, halving and scaling
For water, 2.5 g is 50 drops. For water, 10 g is 200 drops. For water, 25 g is 500 drops.
For water, 50 g is 1,000 drops. The answer scales in a straight line, so doubling the input doubles the output.
Checking and rounding the result
To check the answer, run the sum the other way with the same weight per cup. Starting from 100 drops of water you should land back on 5 g.
Rounding the result to three significant digits gives 100 drops. That is off by about 0.00 percent, which is fine for cooking but worth keeping in mind for large batches.

Common mistakes to avoid
- Treating 20 drops per mL as exact. It is a rule of thumb.
- Using it for medicine doses. Use the dropper or syringe supplied.
- Forgetting the liquid. Oil and honey change the grams per mL.
- Counting drops from different droppers. They do not match.
