Review on 📐 Enhancing Education with Metric Stainless School Architect Engineers by John Springer

These are good light weight rulers. Hanging holes are good. They're 1.01 inches wide and 0.028 inches thick, making them a little bulkier than a machinist's scale, but better for general work and thin enough for accurate measurements. I'm fine judging by my calipers. The 1-inch width allows for large, easy-to-read numbers and tick marks. This was facilitated by the presence of inches on one side and centimeters on the other. This allows for larger numbers since you don't have to have two groups of numbers on each side. The nicest thing is that they start at zero at the end of the ruler (rather than about 1/8 inch from the end like many available) so you can measure right from the inside corner.
