Science Buddies: "Ask an Expert"

so im working on the kelvin electrostatic generator project and im stuck on the flow rate part. I have a good scale, but the part im stuck on is that the ounces being measured on the scale are not fluid ounces and im not sure how to convert ounces(weight) to fluid ounces to milliliters. so basically how do i find flow rate????

Hi josh peep,

I'm sorry that you're having trouble with this! The good news is that there is an easy way to convert the weight of water to a volume of water by using density. The density of water is 1 gram/milliliter. So, all you need to do is convert the weight in ounces to a weight in grams. The number of grams of water is the same as the number of milliliters of water. If you type "convert XX ounces into grams" (where XX is the number of ounces you measured) into Google, Google will automatically convert ounces to grams.

Let me know if you are still having trouble!

thanks so much!
