Carry your passion for science in your pocket.
This laser-cut, laser-engraved, 0.5 mm enamel-coated stainless steel scientific pocket ruler is designed for passionate scientists and engineers who may find themselves needing a quick straight edge, wondering what's next to Technetium in the Periodic Table, pausing to double-check the 6th significant figure in the speed of light or who somehow forgot the 42nd digit of pi.
Keep it in your wallet at all times so you're always ready to do some science!
1) Imperial and metric straight-edge to 85 mm with machinist ruler to 10-mil resolution (254 um)
2) 12 physical constants and 14 fundamental equations from physics and chemistry
3) Temperature, mass and pressure unit conversions plus trigonometry quick-reference
4) Arc and circle drawing protractor tools with 1/8th inch or 5 mm resolution
5) Full periodic table with atomic number reference in each period (row)
6) Phone stand slot (insert another sturdy credit card)
7) 42 digits of Pi (because we could)
8) QR code which links to rotating monthly Easter-eggs on a hidden GLG page
9) Fits any normal credit card or ID holder. TSA compliant and more compact than a standard 6" engineering scale ruler.
Makes for a perfect unique gift for scientists starting school or at graduation!

Ready when you are
This thing is great! It’s nice and sturdy, well made, and being in forensic engineering means always having an awesome product available and small enough to go anywhere! But certainly doesn’t skimp on usefulness. Definitely gonna recommend to more people. Awesome idea and product.

A textbook in your pocket
My brother is in the middle of a college degree in engineering and asked for a "cool ruler" for Christmas. I got him the Pocket Engineer and he said it was his favorite gift this year! He loves that he can take it to class and to his internship and have so much info on hand. It's sturdy and well-made and the printing is very clear!
Small but mighty
I bought 2 of these for high school graduates getting ready to enter college in engineering. Even though I bought these as little bonus gifts to the main presents, the students were most excited about these!
