Em (12pt) to Millimeter (Em (12pt) to Millimeter)
Result
4.233333333 Millimeter
Formula
Millimeter = Em (12pt) × 4.233333333
1 Em (12pt) = 4.233333333 Millimeter, and 1 Millimeter = 0.2362204724 Em (12pt).
In CSS and desktop publishing, 1 inch = 72 points = 96 pixels, so 1 px = 0.75 pt. The em is relative to the current font size; this converter assumes a 12 pt base.
Worked examples
- 1 Em (12pt) × 4.233333333 = 4.2333333 Millimeter
- 10 Em (12pt) × 4.233333333 = 42.333333 Millimeter
- 100 Em (12pt) × 4.233333333 = 423.33333 Millimeter
Common mistakes
- CSS pixels are reference units, not physical screen pixels; high-density displays draw several device pixels per CSS pixel.
- An em depends on the font size it is used in. Change the base and every em value changes.
