Rulers for model scales

[junkyardjeff]

I am going to be building some parts I need to get accurate for 1/25 scale and was wondering if rulers are made for the model scales.

they are. I have one for MRR and one that has both 1:25 and 1:24 scales. check with your LHS or look under tools for on-line hobby shops. Another option is a calculator and digital calipers.

They "do indeed"!      I got this treasured item from an Awesome gentleman Tom Geiger I meet at NNL 40 in Toledo.

There's a multitude of different scale conversion rulers available. However a regular metric ruler is excellent for basic 1:25 scale work as 1 mm close to equals one scale inch (1 inch = 25.4 mm). In most cases the miniscule discrepancy will not be visible to the naked eye.

Lacking a dedicated scale ruler I use the tool on  Online Scale Converter Tool - Scale Modelers World often.  Works great for me.

I could use one of those!

I just run metric conversions in my head. 1 mm = 1 scale inch. I have tricks I use to get close quickly.

Example, if you want to convert 1.2 mm to inches, just go with significant digits, 12 x 4 = 48. Shift the zero over 3 places to the left yields .048".

I use the metric system quite often over the US system.

I just use a calculator.  🤨

Yes, and a $20 digital caliper.  It is made of stainless steel and accurate down to 0.001" (resolution 0.0005"). It does metric too. Got it over 20 years ago at Harbor Freight.  I couldn't model without that vital tool.

Mine wouldn't hold to US measurement, it kept reverting to metric. I found it easier to go metric than fight it..

No problem. Digital calipers have metric/imperial button on them to instantly show the measured dimension using both systems. Mine stays with the system I selected until I change it. As you mentioned, you can also keep switching between them without affecting the measurement. Basically it is a built-in unit conversion.  Very handy. It is one of the most useful tools in my toolbox.

I know you were asking about 1/25, but I shared this in case it could help someone else..
