and it was talking about how much a scale model would weight if you knew the weight of the orig. The maths went like this:

To find your models weight in lbs.

If your ship weighs 29,700 tons, you times that by 2240 (as in 2240 lbs to a ton) and you get the originals weight in lbs as finding your models weight in tons will be near useless.

Then you find out your scale as a ratio, whether it's 1:128 or 1:144 or 1:96, whatever, you multiply this figure by itself 3 times.

So LION was 29,700 tns, x 2240 (lbs) = 66,528,000lbs. LION was 66,528,000 lbs.

My scale is 1:144. So: 144 x 144 x 144 = 2,985,984

Now get you calculator out and divide the lbs out by the scale: thus:

66,528,000 divided by 2,984,984 = 22.28.

Thus a 1:144 LION will be/should be 22.3lbs. (rounded up)

Now there's a calculation for speed as well.
