How many mL is a single drop?
Pharmacists have since moved to metric measurements, with a drop being rounded to exactly 0.05 mL (50 μL, that is, 20 drops per milliliter). In hospitals, intravenous tubing is used to deliver medication in drops of various sizes ranging from 10 drops/mL to 60 drops/mL.
The average volume was 0.05ml. According to the results of various experiments conducted by the pharmacy, 1 liter gives an average of 20 drops per liter.
By conducting various experiments, pharmacists concluded that 1 ml gives an average of 20 drops per ml, which is 0.05 ml per drop.
The accepted average volume of a drop of water is exactly 0.05 mL (20 drops per milliliter).
For a 5 ml bottle, that means you could expect to get between 75 and 150 drops, with an average of 112.5.
Drop | Milliliter [mL] |
---|---|
0.01 drop | 0.0005 mL |
0.1 drop | 0.005 mL |
1 drop | 0.05 mL |
2 drop | 0.1 mL |
The rate is measured by counting the number of drops that fall into the drip chamber each minute. Macrodrip tubing is wider, producing larger drops and is available in three sizes: 10, 15, or 20 drops per mL (gtt/mL).
Tips for Measuring Essential Oils
There are approximately 20 drops in 1 milliliter. These measurements should be considered estimates. Not all essential oil drops are equal; differences in viscosity will impact the volume of an oil that holds together in a drop.

Full dropper is 1ml = 37mg of CBD per 1100mg 30ml size bottle. For example, your pet is 200lbs which means it will need 35mg of CBD twice a day. So according to the dropper measurements, it's a little less than a full dropper twice a day.
How much is a mL?
A milliliter, abbreviated as ml or mL, is a unit of volume in the metric system. One milliliter is equal to one thousandth of a liter, or 1 cubic centimeter. In the imperial system, that's a small amount: . 004 of a cup .

Travatan Z — another glaucoma medication — comes in either 2.5mL or 5mL packaging, which gives an idea of how much mileage you can expect out of it. A common rule of thumb is that for every milliliter of eye solution you have, there are roughly 20 drops.
Full dropper is 1ml = 37mg of CBD per 1100mg 30ml size bottle. For example, your pet is 200lbs which means it will need 35mg of CBD twice a day. So according to the dropper measurements, it's a little less than a full dropper twice a day.
To calculate the drops per minute, the drop factor is needed. The formula for calculating the IV flow rate (drip rate) is total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL), which equals the IV flow rate in gtts/min.
