**Physics, Astronomy & Cosmology / WHat is the the fuel consumption of the SSME?**

God I’ve done a lot of rocket stuff.

Anyway, I’ve been doing a bit of looking on the internet, and I think I understand that ISP = Thrust/fuel weight flow rate. I know that the SSMEs have a thrust of 480,000 lbf at SL. I can’t remember their ISP (a quick Wikipedia will do the trick I’m sure), but since I’m a little confused about the units, could someone please use this info to tell me how many kilos (or any other unit of mass) of propellant an SSME (at max thrust) burns per second? Cheers.
