fuel flow rate (in kg/s) = thrust
(in thousands of Newtons). E.g.
an exhaust of 7500km/s at
1kg/sec produces thrust of 7.5
million N. Plugging in the general
equation F=ma, this accelerates
a 1000 ton ship at roughly 7.5
meters per second, or about .75
Earth gravities.

You're off by a factor of [merely] 1,000. The formula gives results in kilonewtons, not newtons.
