A nifty little reel out of my collection that has a lot of good tips for taking accurate measurements with a steel ruler. As always I transferred this film with my own Telecine ans did color correction to taste. Enjoy!

Decimal inches [shudder]. 😁
Love the films!
🍿😁 thanks Fran. Do you have anything on Vernier calipers?
Never saw a 1/10th scale ruler. It's a nod to the simplicity of the metric system.
We really tried really, really hard to not switch to metric.
Decimal inches… just a tacit admission that metric is better!
worked as a CNC machinist back in the 90s, still have my trusty 6" with the sliding pocket clip..fun fact: since it has metric & english, technically it's an analog computer,(albeit very specialized) since it can convert from mm to inches, 32nds, etc & vice versa, plus the sliding clip is like a 1 number memory.
So familiar. Common for me to use my scale under a low power microscope to check chamfer width, etc., when I was machining AMPEX parts in the early 80's at a shop in Redwood City, CA. Good times.
I once knew an old time machinest who HATED the metric system. He said it just had too many odd numbers after the decimal point. But that's because he was only working off of drawings of things designed with inch measurements and converted to metric. So, 0.38" becomes 9.652 mm. He was OK with "lots of digits" for things he was used to seeing like 0.375". He didn't realize that something designed from the start in metric has more friendly numbers.
I feel the main reason for the chest pocket in a machinist shop coat is to have a place for the 6 inch scale.
*laughs in metric*
“Upon receiving their first steel scale, all boys will immediately measure the same item, and it’s not a machine part. Many will use the metric scale, because the numbers become larger much sooner. Luckily, girls have no need to measure anything other than flour and milk, so they have no need for a steel scale, and can instead use one of their pretty teacups.”
This is great also sort of a good demonstration why in certain fields they use the metric system something I think scientist Fran knows because it makes some things easier10 inches 250 thousandths which would be 256.25 mm or something along those lines so cabinet makers often use metric system for the same reason also we had a steal tape measure that had metrics and inches in the thousandths before we ended up not using it Woodworkers rulers have what's that 64's
