3.1.7. TeXUnit¶

This module provides functions to convert units used in the TeX world:

• mm stands for milimetre,
• in stands for inch which corresponds to 25.4 mm,
• pt stands for TeX point, there is 72.27 pt in one inch,
• sp stands for scale point, there is 2**16 sp in one pt,
• dpi stands for dot per inch.

The DVI format uses the measure 100 nm as base unit. A scaled point is defined as a fraction:

• num = 2.54 * 1e7 = 25400000
• den = 7227 * 2**16 = 473628672
• 1 sp = num/den = 5.4 nm

For a resolution of 1200 dpi, a pixel measures 21 um.
