How to convert atomic units of length to twips
1 a.u. of length is equal to 0.000003000059778 twips, and 1 twip is equal to 333,326.6914 atomic units of length. To convert, multiply by the conversion factor:
twips = atomic units of length × 0.000003000059778
twips = atomic units of length ÷ 333,326.6914Example: convert 15 a₀ to twip: 15 × 0.000003000059778 = 0.00004500089668 twip.

About the twip
A twip is one twentieth of a point, or 1/1440 of an inch (about 17.6 µm). It's used internally by Microsoft Word, RTF files and older Windows APIs.
