Scale Conversion Tool

[johndon]

I make a living writing computer software but, until now, have only ever done this for Windows desktop PCs.  As software moves inexorably to ‘the cloud’, I figured it was about time I learnt how to write applications that run in a web browser and figured, while I was learning, I may as well create something useful and this has turned in to a Scale Conversion Tool.

 

It has the following features:

 

• Convert Actual Length to Scale Length.  Enter a ‘real’ length in the units of your choice and it will be converted to the equivalent scale length in whatever units you choose.
• Convert Scale Length to Actual Length.  Same as above but the opposite way round.
• Convert Scale Length to Scale Length.  Enter a length in one scale and have it converted to other scales.
• Convert actual curve radius in chains to scale radius in a choice of units.
• Convert Imperial to Metric.
• Convert Metric to Imperial.
• Convert Thou to mm.
• Convert mm to thou.

 

Scales supported so far are listed below although you can enter your own scale ratio for most of the calculations if you wish.

 

• 2mm scale (US/EU N) - 1:160
• 2mm scale (2mm FS) - 1:152.3
• 2mm scale (British N) - 1:148
• 3mm scale (British TT) - 1:101.6
• 3.5mm scale (HO) - 1:87.1
• 4mm scale (OO, EM, P4) - 1:76.2
• 7mm scale (O) - 1:43.5
