There are approximately 7,680 drops in a gallon.
90,840.
1 gallon (US) is about 75,708 (75708.23568) drops.
16 oz is a pint, 2 pints per gallon, so 2 drops.
Facts:120 drops = 5mL1 gallon = 3785 mL* 90840 Drops in 1 GallonIf a faucet dripped once a second how many gallons of water would it waste?It would waste 347 Gallons of water a year!Facts:1 year ~ 31,536,000 seconds24 drops in 1 mL1 gallon/3785 mL X (1 mL/24 drops) X (1 drop/ 1 s) X (31,536,000 s/ 1 year) = 347.1598415 gallons / year
10 drops = 0.648 cc 1 gal = 3.785 liters do the math
To purify a gallon of water, you can use 8 drops of bleach if the bleach concentration is 8.25%. Mix well and let it sit for at least 30 minutes before consumption.
Answer about 13 gallons depending on your assumptions of how many drops per gallon.Several methods to figure this out:1 million drops of water is 1666.667 fluid oz. There are 600 drops per fluid oz and 1,000,000 divided by 600 is 1666.667(last digit is rounded)1666.667 oz if about 13 U.S. gallons or if you prefer metric it is49.289 litersMethod 290840 Drops in 1 Gallon ( but that value depends on water temp and other factors)90840 Drops/1 gallon=1,000,000 drops/x gallons90840x=1,000,000x=11.0084 gallonsSo this method gives 11 gallons and if we want to know how many cubic inches that we note that:1 gallon of water is 231 cubic inches. So 11.0084x231=2542 cubic inches.______I found another professor give this example:http://jwilson.coe.uga.edu/emt668/EMAT6680.Folders/Howard/Million.Drops.of.Water/Million.Drops.of.Water.html10 drops of water = 1 milliliter and: 10,000 drops = 1 Liter then: 1,000,000 drops = 100 Liters and my reference quoted that: 1 Gallon = 3.5 Liters, so 1,000,000 drops of water = 28.5714 gallonsMethod 3The example above 10 drops per ml, and of course you can easily imagine that the size of a drop of water will not be uniform. It depends on temperature and the dropper and many other factors.Most people use 15-20 gtts( drops) per ml, usually 20.So the slightly larger value in this result comes from the fact that the drops are much bigger, 10 per ml instead of 20. Divide 28.574 by 2 and the you have 14.2 gallons. Also 1 US gallon = 3.78541178 liters so using 3.5 is a low estimate.So here is the same calculation as above using different assumptions. The example below uses 3.785 liters per gallon and 20 drops per ml.20 drops of water= 1 milliliter20,000 drops = 1 liter1 gallon is 3.785 liters.so(20,000 drops/1 liter)(3.785 liter/1 gallon)=75,700 drops/gallon(compare this to 90840 used in the first part above)75,700 drops/gallon=1,000,000 drops/X gallons.Solve for x75,700X=1,000,000and the answer is 100, 000 drops is 13.21 gallons
Wikipedia says that a metric drop of a fluid is 1/20 mL, which is 1/20000 L. In one gallon, there are 3.7854 L. So by dividing the 3.7854 L by the 1/20000 L of a drop, the result gives 75,708 drops. This can change as there are different size drops.
Since 1 gallon equals 90,840 drops and 1 Olympic sized swimming pool has 660,430 gallons, there are 59,993,461,200 drops in an Olympic size swimming pool.
An US gallon has 3,485411784 L; multiply with your value to obtain the total volume. Aassuming that a drop has 0,000 060 L divide the total volume with the volume of a drop and you will obtain the answer.
Fish tanks can be any size; from 1 gallon bowls to 500 000+ gallon public displays. about an inch from the top should be fine, depending on filter, size of aquarium etc.
