Thumbs up How Big is 1mm?

Found this tip in Rio Grande catalog:

Take a US Quarter

The letters in UNITED STATES OF AMERICA = 1.5mm
The letters IN GOD WE TRUST = 1mm
The Mint Mark = 0.75mm

Damn, I will have to adjust my scribe marks. I knew there was a reason I kept getting OOR pens

Well sure if you are using your fancy sliderule. Show-off.

Old joke:
Fresh engineer with new sliderule. You guys with your calculators should learn to use a sliderule as they are much faster.

Guy: Ok lets try this calculation:
What is 2 times 2?

Guy: =4
Sliderule guy: 3.958

An easier way to find out how big a mm is..

Look at a ruler!

(I'm sure you can get non-US rulers on ebay)

Unit converter 1.4, one of the handiest little programs for your desktop- it converts about any measurement you want converted to whatever you want it converted to (but not raisins)

Tim Johnston Development LLC

I use it all the time.

So does Google, and I usually have my browser up, so it's easier even than the Windows Calculator. (Speaking of which, recent versions of Calculator also do most conversions, so that's available for Windows users.)

Anyway, on Google you just enter the measurement you have followed by "in" followed by the measurement you want. Try entering

350 g in oz
1 mm in inches
1 furlong in mm

It also works in the search bar at the top of my browser (which I've set to Google).
