No worries man. Things just need to be more clear. So what you guys are really saying is that your yogurt container can only be measured in milliliters by using only water weight and nothing else? If that's the case, the other posted were correct.
it's not that your container can only be measured a certain way
I added that "confusing" part in order to give people a way to know for sure if the container they are using is allowed under the rules, mostly because not everyone is USA peeps and not everyone gets the same brands and containers. the "confusing" part:
Now let's just say you have a yogurt / pudding / jello container you want to use and can't tell if it is acceptable or not... here is now to tell;
250 mL = 1 cup
Fill your container with water to the VERY top, then measure this liquid in either a graduated cylinder that measures in mL or a standard cup. If ALL the water from your grow container fits in the measuring cup or within 250 mL on the graduated cylinder - then your container is acceptable.
Also, you can use a scale to measure the mass of water in your container (1 mL of water = 1g mass). To do this simply weigh your container, tare it to zero, then fill with water and weigh again. as long as your container holds a mass of no more than 250g of water then it is acceptable.
This part isn't really in the RULES it's afterwards, just a clarification (that backfired apparently) in order to provide a way to standardize the container being used without really telling people EXACTLY what container to use, just trying to lay out some parameters;
IF you container holds MORE than 1 cup of water OR 250 mL of water
THEN it is not within the parameters
IF the mass of the water that fills completely your container is more than 250 g
THEN it is not within the parameters
these tests have NOTHING to do with the medium (or mass/ volume of medium) that fills your container, instead only to do with the container itself and it's maximum volume of medium.
Dr.King, i urge you to jump in head first and enjoy the ride.
