How Many Drops Are in a Milliliter?
To find out how many drops are in a milliliter, we need to establish how many times we have to multiply the number of milliliters in a drop (0.05 ml) until we reach 1 ml.
Conversion Calculation
So, 20 drops is the equivalent of 1 ml. One drop is equal to 0.05 ml.
Drops to Milliliters Conversion Chart
Here is a chart with the most common and practical conversions showing how many drops are in various milliliter amounts:
| Drops | Milliliters (ml) |
|---|---|
| 1 drop | 0.05 ml |
| 2 drops | 0.1 ml |

How Many Drops Are There in a Liter?
A liter is the equivalent of 1,000 ml. We also know you need 20 drops to reach 1 ml. In order to calculate how many drops are in a liter, you have to multiply the number of milliliters present in a liter by 20 drops.
Calculation
So, a liter is the equivalent of 20,000 drops. That's a lot of drops to count one by one, but this is precisely what this drops to ml conversion calculator is for — so you can save some time with your calculations!
How Many US fl oz Is There in a Drop?
We know now that 1 drop is 0.05 ml. But how much does that represent in US fl oz?
Calculation
1 ml is equal to 0.034 US fl oz, and a drop is 0.05 ml, so:
1 drop is therefore equal to 0.0017 US fl oz.
How Can I Figure Out How Many Drops Are in My Cup?
One cup contains 237 ml. We also know how many drops are in 1 ml — 20 drops. So you need to multiply the volume of the cup by 20:
Calculation
A cup contains 4,740 drops. Try entering 237 ml into the drops to ml conversion calculator to check for yourself!
How to Measure Milliliters at Home
How can we measure milliliters at home? Unless you are ready to count drop by drop the volume of your liquid, there are some easier and faster ways to do it:
Use a Measuring Cup
You probably have one in your kitchen. Those cups have indications showing how much liquid you need to pour to reach the number of milliliters you need.
Use a Syringe
Syringes are similar to measuring cups but usually are for smaller and more precise volumes of liquid. They have indications on the side about how much liquid you have inside.
Measure with a Scale
You can use a volume to weight converter to determine how much the amount of liquid weighs, and then use a scale to weigh your liquid. For water-based liquids, 1 g ≈ 1 ml.
Look at the Bottle
Bottles of liquid usually have the number of milliliters written on them; you won't need to do any drops to milliliters conversion.
Practical Applications
This converter is essential for various practical scenarios:
Essential Oils
Calculate how many drops of essential oil you need to put in your homemade candles, diffusers, or DIY products for them to smell like paradise. Essential oils are often measured in drops for precise aromatherapy applications.
Medications
Some liquid medications are measured in drops. This converter helps you understand how many drops you need to take to reach a specific milliliter dosage. Always consult a healthcare professional for medication dosages.
Precise Measurements
When you need very small, precise liquid measurements and only have a dropper available, this converter helps you determine the exact volume in milliliters.
DIY Projects
Perfect for DIY projects, crafts, and recipes that require precise liquid measurements. Convert between drops and milliliters to match your available measuring tools.
