How to Use These Calculators

These calculators handle the geometry behind part programs and inspection. True position, point-to-point distance, and angle between points help check feature locations against a drawing, while hole pattern spacing and bolt circle coordinates turn a pattern callout into the X and Y positions a program needs.

Hypotenuse, chamfer depth, and arc length solve the right triangles and curves that come up when programming edge breaks and radii. The degrees to radians converter is handy when a formula or spreadsheet expects radians. Check the units on every input before relying on a result.
