Typography converter
Points, picas, ems and pixels. 6 units, converted from one table of exact factors.
—
1 point in every other typography unit
Computed by the same engine that runs the converter above, so these can never drift apart from it.

What each unit actually is
Most converters give you a number and stop. Where a figure is exact by definition we say so, and where it is an average or shifts with conditions we say that too — that is usually the thing you needed to know.
| Unit | Symbol | What it actually is |
|---|---|---|
| point | pt | A 72nd of an inch in modern desktop publishing. Older typographic points were slightly different. |
| pica | pc | Twelve points. |
| inch | in | Exact, given the modern point. |
| millimeter | mm | |
| pixel (96 dpi) | px | Only true at 96 dpi, which is the CSS convention rather than a property of any screen. |
| em (12 pt) | em | An em is the current font size, so this is only right when the type is 12 pt. |
