"Model Scaler" Smartphone App
Posted by BigE68 on Thursday, June 21, 2012 6:26 AM

I stumbled across a free app on my smartphone marketplace by Woodland Scenics called "Model Scaler". It is geared towards the model railroad market giving you conversion tables betweeen different railroad scales, but it has a "Custom Scale" field where you can input any scale you want to use. It will convert between "Actual" mm, cm, in, ft, yds, or m to the "Model" mm, cm, in, ft, yds or m.

The app shows that, in model railroading, "G"-scale is 1:24. So you could just select "G-Scale" from the selection list or just type it in the "Custom Scale" field.

So if you are using 1:25, you just input "1:25" in the "Custom Scale" field, and then it will take you to the conversion field. You just input your dimension and select the unit of measure, and it will convert it for you. If you have the "scale" dimension, you can insert that value in the bottom field first and it will give you the "actual" dimension.

I didn't know if anyone had mentioned this app before, but it seems like it could be a handy thing to have if you didn't want to do the math yourself. I would be interested to know if anybody has found any other apps that they are using.

I grew up with feet and inches, and now Oz is metric, 1" = 25.4mm.  Very close to 1/25.  So if I want a 4" cut in 1/25 or 1/24 scale I simply measure 4mm, easy.  Cheers

The best thing about this app is that it weighs most things accurately and precisely. Another positive thing is you can move to SD support through it. It has the strength to zero the scale and this is a plus point too.

I don't have a smartphone and am not interested. As a retiree they are far too expensive and go 'out of fashion' too quickly. And those who have them here in the UK, just keep walking into you while they constantly 'GAWP' at there phones, not looking where they are going!

Walking while looking at phone is a world wide problem, though I did take opportunity to scare the crap out of guy walking and staring at his phone.  I kind of got sick pleasure out of that. :-)
