Unit converter.
The units designers actually bounce between: length, weight, volume, and board caliper. Type in either field and the other updates. Caliper points here are board points (1 pt = 0.001 in), not typographic points.
Length.
Inches, millimeters, centimeters, feet.
Weight.
Ounces, grams, pounds, kilograms.
Volume.
Cubic inches, cubic feet, liters, milliliters, fluid ounces.
Board caliper.
Points, mils, inches, millimeters. Board points and mils are the same thing (0.001 in); paperboard is usually quoted in points, plastic film in mils.
Disclaimer: These tools were built at my desk to keep the answers I need in one place. I’m sharing them in the hope that they make your design process a little easier too. The math is checked against published standards and real-world experience, but specs change and materials vary. If you spot anything that seems off, please email me at donna@donnakadell.design and I’ll take a look.
Enjoy.
