Quick question,. I have the granular TSP and need to know what 2lbs would be in cups. I watched the first video listed and it showed one cup to 5 gal of water and didn't say if that cup was liquid or granular. At this point I am just going to add half of the box but would like to know for further reference. Thank you.

The net weight of the box is 4.5 lbs.-2.04 kg
