:) :) :)Hello everbody,
You might think that the title of the subject a bit odd......well, scale calculations has never been one of my better subjects. Its like when I was at school in the early fifties, Algebra was gobblegook but in those days you were not allowed to question the whys & wherefores just get on with it. I just cannot understand why one has to substitute numbers for letters so I could never get my head round them.
The same goes for the scales on model boats. I read that a scale is say 1:64 which means that the model will be so many mm long. How is this worked out? Is there a formula to work to. Apart from this I am confident in all other aspects of measurement(I think). Love the Forum. regards Ceres.  :) :)

It just means that the model will be 64 times smaller than the real thing

... or a backwards view of it would be that 1mm (or inch or foot or metre or yard etc.) of the model, would be equvalent to 64mm (or inches, feet, metres or yards etc.) on the real thing!

OR if you put 64 of the models touching bow to stern in a straight line, they would go from one end to the other of the full size vessel.

I read that a scale is say 1:64 which means that the model will be so many mm long. How is this worked out? Is there a formula to work to.

Example :-

The average height of a man is lets say, 6 feet tall or 72 inches.
If you divide this figure by the scale, in your case 64 then the result is the size of a figure for you scale i.e. 1.125 inches or to round it off, just over 1 inch tall.

If you have a model figure of which you dont know the scale, then take the full height (in this case 72 inches)  and divide that by the size of the model figure (1.125 inches) and you'll get the correct scale (1:64).

It gets a little more complicated when converting from one scale to another but it can be done with a bit more calculation.

That reminds me of what we used to say about the sixth form of a local girls' school many years ago, that if all the girls were laid end to end, nobody who knew them would have been all that surprised .....

Have a look at the link below for more info on scale, including scale calculators which include scale speed calcs.

Not sure how accurate the figures are but maybe worth a look.

                                                                                   64 GOGS laid end to end equals 1 ??                                 

[RickF]

64 GOGS laid end to end equals 1??

= 1 real challenge for Evel Knevil !

I'll still go for the end to end sixth form girls in gymslips. That's my kind of challenge.

Just taken a look at the speed calculator on the link and its wrong. All its doing is dividing the speed by the scale. Scale speed is the speed divided by the square root of the scale.

Johno,

Thanks for pointing that out.

See, you learn somethin every day (or should that be every post ?).
