20 drops equals approximately 1.0 ml
Converting 20 drops to milliliters results in about 1.0 ml. This is based on the standard approximation where 1 drop equals 0.05 ml, so multiplying 20 drops by this factor gives the total volume in ml.
This conversion assumes that each drop contains roughly 0.05 ml, which is a common estimate used in medicine and cooking. The actual volume can vary depending on the dropper or the liquid’s viscosity, but 0.05 ml per drop is a typical standard for calculations.

Conversion Formula
The formula to convert drops into milliliters is: ml = drops × 0.05. This works because, on average, one drop contains about 0.05 ml of liquid. By multiplying the number of drops by 0.05, you get the total volume in milliliters. For example, 10 drops equals 10 × 0.05 = 0.5 ml.
The reason this formula works is that it uses the standard approximation for drops, which is based on the typical volume per drop used in medical and culinary contexts. The multiplication scales the number of drops into milliliters accordingly, providing a quick and easy calculation method.
Conversion Example
- Example 1: Convert 15 drops to ml.
- Multiply 15 drops by 0.05 ml per drop.
- 15 × 0.05 = 0.75 ml.
- Result: 15 drops equal 0.75 ml.
- Example 2: Convert 50 drops to ml.
- Multiply 50 by 0.05 ml.
- 50 × 0.05 = 2.5 ml.
- Result: 50 drops equal 2.5 ml.
- Example 3: Convert 5 drops to ml.
- Multiply 5 by 0.05 ml.
- 5 × 0.05 = 0.25 ml.
- Result: 5 drops equal 0.25 ml.

Conversion Definitions
Drops
Drops are small units of liquid volume typically used in medication and recipes, usually defined as the amount dispensed by a standard dropper, approximately 0.05 ml, but can vary depending on the liquid and dropper used.
Milliliters (ml)
Milliliters are metric units of volume measurement, with 1 ml equal to one-thousandth of a liter. They are commonly used for measuring liquids in cooking, medicine, and laboratory settings.
Conversion FAQs
What is the difference between a drop and a ml?
A drop is a small, often variable, volume of liquid dispensed from a dropper, averaging about 0.05 ml, whereas a milliliter is a standard metric unit representing a fixed volume, making drops less precise for large measurements.
Can I use the same conversion factor for all liquids?
No, the volume of a drop can vary depending on the liquid’s viscosity and the dropper’s design. The 0.05 ml per drop is a general estimate; for precise measurements, specific drop sizes for each liquid are needed.
Why does the conversion sometimes differ in practice?
Because the volume of a drop depends on factors like the liquid’s surface tension and the dropper’s tip size, actual measurements may differ from the standard 0.05 ml estimate, especially with liquids of different viscosities.
How can I improve the accuracy of my conversion?
Use a precise measuring device like a syringe or graduated cylinder for small volumes, or determine the actual volume per drop with your specific dropper and liquid, then apply that value for precise conversions.
Is there a standard for medical drops?
Yes, in medical contexts, a standard drop is often considered to be 0.05 ml, but some medications or applications may use different standards, so always check the specific instructions or measurements provided.
