What I am asking is that if I just have a bucket of salt, how much will I need to make a gallon of water of standard SG. IO says 1/2 cup, but that is irrelevant to me as I don't know how big of a cup to use. Hence I am asking for the metric amount that a cup holds. If I know the gms or ounce, then I can measure it out.

Look on the pail, says pail makes 160g (605l) and weighs 48lb (21.7kg) can figure it out with a little math but a cup traditionally is 8oz (volume) or 250ml.

I will go ahead with a measuring cup and measure out 8oz for 2gallons of water. If the SG is fine, then I am good.

Thanks everyone.

I never measure, just throw it in and top it up until I hit 1.025 on the refractometer.

2.5 cups will make 5gal of salt water. Use a 8oz cup as Mark stated

I do mine by weight 1.5 pounds of IO to 5 gallons water. you will need 19.5 pounds of IO salt.

Thanks to everyone for their help. Finally I can get my tank up and running.

I took a container that was about the right size for the volume of water I wanted and threw that salt filled up to the top into the bin. Then filled it with water until I hit the right salinity. Put a mark on the bin and now I just fill the bin with water to the line and throw the salt in from the container and it is the same always.
makes changing the water a bit smoother.

You use a Measuring Cup. 1 cup is a standard unit of measure. they make measuring cups in 1/4,1/3, 1/2, 1 cup measurements.

That was a painful thread to read
