Subject: Scale - Units?

I was just reading a post where the author was carefully refering to range in
units, rather than cm or inches. I quite like the fact you can use whatever
scale fits your table.

I was wondering. What game scale is a unit? Since thrust seems to be between
2 and 8 units/turn, it should be possible to refer to that as a speed. I

guess you'd need to know how long a turn is. Do we know how long a turn is?

How far is a unit (1cm or inch on the table)? How long is a turn? What rate of
acceleration is 1 thrust unit?

It's nice you can play a game without worrying about this stuff though.

I worked this out once from the planet radii and orbits in More Thrust. I
can't be bothered to do it all again, or even to look up the original text
file. But the units of length are 1000 km And the units of time are about 20
minutes.

The units of Thrust are actually infinite! As acceleration is applied
instantly dt goes to zero and so dv/dt goes to infinity! If the
acceleration was applied over the whole turn then about 0.7 m/s^2

Obviously some intermediate acceleration would be more realistic. I've always
favoured 1 thrust = 0.5g That makes Thrust 8 = 4g. Which military crews should
be able to withstand for reasonable periods of time.

Yep. No game with a hardwired scale could be used to game out Trek battles
(which seem to take place at mere hundreds of metres) and battles from real SF
backgrounds.
