So, someone did something like this, but for Cock Vore:

>How much cum would a given prey produce in US gallons since we use those to hold our milk in my area?
>So we need to find a few numbers, the density of milk/semen, and how much they would weigh when taking up a US gallon (~3785.41 ml) of volume. Note that cubic centimeter and milliliter are the same thing in this case. So we multiply density and volume to get the mass. So if it's grams per cubic centimeter, we just multiply it by the amount of cubic centimeters in our gallon.
>Milk Density - 1.033 grams/cm3 x 3785.41 cm3 = ~3.9 kg which converts back into 8.6 pounds which is the stated number on google, so our numbers are right.
>(normal) Semen Density - 0.9982 g/cm3 x 3785.41 cm3 = 3.778 kg = 8.32 pounds
>But my friend has special cum. Not the white cloudy stuff humans spew, but real cum. The extra thick and creamy kind! Seeing as his cum was thicker, we assumed it was more dense than milk being 8.6 pounds a gallon and the thicker maple syrup being 11 pounds as an example. So his thick cream was assumed to be around 9.5lbs/4.3kg per gallon based on that.
>So now we know if a gallon were filled with these fluids, how much they'd weigh.
>Milk: 8.6lbs/4.3kg
>Normal Semen: 8.32lbs/3.77kg
>Creamy Semen: 9.5lbs/4.3kg
>Now that's great and all, but how much cum would a given prey produce? Since we know how much a gallon would weigh when filled with a certain fluid, and has a specific volume, we can use that as a yard sick for our preys volume. Since they transformed into the fluid in question, they'd inherit the properties of that fluid. Thus, if their converted mass is half of a gallons mass of that fluid, they'd take up half of a gallon of space. Of course, we need to know the conversion ratio. To keep the numbers simple, we and my partner assumed the prey skroggling away in his loins would have 100% of their body mass converted into the fluid they are making. So 5lbs of prey make 5lbs of cum. Since we know the mass and density, we can know the volume. To make sure the numbers work, if we take a prey mass of 4.3 which is half of a full milk gallons mass of 8.6, the prey would take up half of a gallon of space if they were converted into milk. See where I'm going?
>So the numbers go: (Mass of prey) Divided by (Mass of 1 gallon of the fluid they are being turned into) = (Number of gallons they'd fill, with 1.0 = 1 gallon)
>Example 45\9.5 = 4.73, or four and three quarters of a gallon filled with that thick semen.
>Why do all this? I was wondering, if something were turned into cum, how much would it make? With this in hand now, instead of guessing how much a cum - a ferret for example would make - or something abstract like a "big load" or "enough to fill a cup!" With these numbers, I can have something concrete. In an example, if we take a prey creature such as a ferret - with an average weight of 2 and 1/3lbs - divided by 9.5lbs to make creamy semen, we get ~0.24 or a little under a quarter of a gallon/liter or ~33fl.oz
