HMHS Britannic

I've been working on this paper model of the HMHS Britannic that I found currell.net and enlarged the model by 250 so that should make this model 1/900?

There is a kit by an unknown German association Heidelberger Modellbau that offers a - rather - basic Britannic model. Fly Model has planned a Britannic / Olympic ersion but so far I have not heard any results. As far as I know there are four 200/250 kits that are suited for conversion: Fly, Wilhelmshavener, Schreiber and JSC

The usual math for scale conversion is:

"Scale you've got divided by the scale you want and then multiply the answer by 100 to get % to print it out at."

Currel's Britannic is 1:1200. So: 1200/900=1.3333 (X100) = 133.33

Print the Currell Britannic at 133.3% to get 1:900.

If printed at 250% the final scale would be 1:480.

I never have been a wizard with math lol. I suppose 1:480 could be correct. What I did was downloaded the ship pages, then in windows image editor, I enlarged the size to 250% Does that still come up to 1:480? Either way I love this model better than the original 1:1200 version!

If you have any clues as to where I could obtain the Heidelberger Modellbau Britannic, please let me know!

It's easy if you think of what the numbers mean:
  1. when one says the scale is 1:X, it means actual size is divided by a reduction factor X; big model = small factor, and vice versa
  2. if you print at Y% of original size, you multiply it by Y / 100
  3. therefore the new reduction factor is smaller. You get it with X / (Y / 100) = X x 100 / Y (remember, divide A by a number larger than 1, you get something smaller than A; by a number smaller than 1, something larger than A)
In your case, 1200 x 100 / 250 = 480.
Conversely, if you want the enlargement for a new scale, just swap the numbers (like in Rubenandres77's answer), and you'll get 1200 x 100 / 480 = 250

Yes. That's another way of getting the same result.
Actually many people do that: enlarge by the desired % in an image editor, and then print. For some it's more practical to do it that way.

Well ok then. Thanks for clearing that up!

Don't trust that much the enlargements on screen or printers, at the end of the day measure the length of your model.
Wikipedia gives an overall length of the Britannic at 269 m / 882 ft 9 in.

Check the length of your model:
1/100269.0cm1/200134.5cm1/40067.3cm1/48056.0cm1/90029.9cm1/120022.4cm

I am curious, what was your result?
