Brilliant tool - would love it if it could also display mils (6400)!
Nice tool, thank you so much
For years and years I've searched for a tool that could measure angles. No learning curve here. Accuracy up to 4 decimal digits. Zero-angle (+ x-axis) rotatable to any angle. Click- nudge to get an angle vertex exactly over a point. Zoomable. There are other options and most are adjustable. Beyond imaginable! No improvements left for me except going outside the browsers!
