SI units are indeed nice. But sometimes it MAY help people's brains to=20
deviate very slightly. But often enough doing so makes things worse=20
:-).
In this case as the "force" being winched was expressed in kg I=20
started with that as a force rather than calling it a mass.

We are of course very accustomed to the mongrel unit "kilograms force"=20
(except for Amercians) as we insist on expressing "weights" in=20
kilogram rather than Newton. This would be eg the equivalent of asking=20
for a 1/32 slug of tomatoes.

If one was were to start talking about cgs units for 'weight' one=20
could dyne out on the results for a considerable period.
