This page converts drops into milliliters using the factor 0.05, and shows the reverse figure alongside it. Both units measure volume, which is why one number does the whole job.
The metric drop, standardised at 0.05 millilitres, or twenty drops to the millilitre. One thousandth of a litre, equal to one cubic centimetre.
US and imperial measures share names and do not share sizes. The imperial gallon is 4.546 L against the US 3.785 L, and the imperial pint is 568 mL against 473 mL. A recipe or fuel figure is 20% out if the wrong gallon is used, so check which side of the Atlantic the number came from. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into milliliters, which is usually more useful than the bare number.
The formula
drops- The amount you are converting, in drops
0.05- The exact number of milliliters in one drop
milliliters- The converted result
How it works, step by step
- Enter the value in drops.
- It is multiplied by 0.05, the exact factor between the two units.
- The answer is shown in milliliters, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
A teaspoon: 98.6 gt in milliliters
A teaspoon comes to about 98.6 gt. Multiplying by the factor: 98.6 × 0.05 = 4.93 mL. Dividing the answer back by 0.05 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
A wine bottle: 1.5e+04 gt in milliliters
Take a wine bottle, roughly 1.5e+04 gt. The conversion is a single multiplication — 1.5e+04 × 0.05 — giving 750 mL. Because the relationship is proportional, doubling the input doubles the answer to 1500 mL.
How to read your score
Frequently asked questions
How many milliliters are in one drop?
Exactly 0.05. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert drops to milliliters?
milliliters = drops × 0.05. Reversed, drops = milliliters ÷ 0.05, which is the same as multiplying by 20.
Which is the bigger unit, the drop or the milliliter?
The milliliter. One drop is only 0.05 of a milliliter, so it takes 20 drops to make one milliliter.
What does this quantity actually measure?
Both units measure volume. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a drop?
The metric drop, standardised at 0.05 millilitres, or twenty drops to the millilitre.
What is a milliliter?
One thousandth of a litre, equal to one cubic centimetre.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
