Scale measurements

[JR]

Hello all.
I have a scale 1.35 rule from RB, used many times. Today while measuring the opening for some gates I had a look at

https://www.ginifab.com/feeds/cm_to_inch/scale_converter.html

Now when I measure with the rule against my normal ruler.


The lower one and the scale version


When I measure the scale length and put it into the conversion chart I get.

Scale Ratio	:
Real Length	mm cm meters km inches feet yards miles nautical miles
Scale Length	mm cm meters km inches feet yards miles nautical miles

89 × 1 ÷ 35 = 2.5428571429 mm

While using the rule it comes out at over 3 .010 mm .
Any reason why and where am I miss using .
Here is the photo just taken of the scale rule with the normal size showing the 89mm and the scale measurement.


Confused to say the least with the scale converter.

Hi John
Can't help, sorry, but that Scale Conversion Calculator is really useful.

To me, the ruler is incorrect. 89 mm divided by 35 is 2.54, as given by the calculator.
if the answer was 3, as given by the ruler, then 3 x 35 should give you 89, which it obviously doesn’t. The scale ruler is actually giving you the scale distance for just over 105 mm. Are you sure it’s not actually a 1/30 scale rule?

John,
Download a free app called Hobby color converter. As well as having a really good colour converter it has an excellent scale converter as well.

Hmmmm,Not sure what`s going on there John:thinking:,
HOWEVER,Judging by the date on your Scale ruler,(Pre 2016)...... i`d say "BLAME BREXIT" ..........
For everything else that goes wrong it seems to be the culprit these days!!:tears-of-joy::tears-of-joy::tears-of-joy:

That's what I've thought Jim, so judging by what Tim says and my own measurements the rule from RB is incorrect.

To me, the ruler is incorrect. 89 mm divided by 35 is 2.54, as given by the calculator.
if the answer was 3, as given by the ruler, then 3 x 35 should give you 89, which it obviously doesn’t. The scale ruler is actually giving you the scale distance for just over 105 mm. Are you sure it’s not actually a 1/30 scale rule?

My thought exactly Tim, its has printed on it 1/35 .

Now that's a thought so using the compound interest rate divided by 25 x 12 x 135 it works quite well .I blame the French .
