The 0.1 is a mistake! Should be 0.005 because that’s the Gs I specified. I rewrote the example and that got left in by mistake. Fixing it now above.

Yep, T/W is unitless, so multiplying by any weight gives you the thrust for an engine of that weight. All THS drives are 4 tons per space, so multiplying 4 by the T/W is the tons of thrust.
