About these units
Petameter (Pm)
A petameter is 10¹⁵ meters and begins bridging the gap between solar system scales and the nearest stars. Distances between stars, the size of large cosmic structures, or the wavelengths of extremely low-frequency electromagnetic waves may be expressed in petameters. For example, a light-year is about 9.46 petameters. Petameters rarely appear in everyday astronomical writing because traditional units like light years and parsecs are more intuitive to astronomers and the public. However, the unit's alignment with SI conventions makes it essential in scientific computation and large-scale modeling, especially when dealing with cosmic distances while maintaining strictly metric consistency.
Twip (twip)
A twip is a twentieth of a point, equal to 1/1440 of an inch. This extremely small unit originated in computer typography, particularly in early word processors and GUI layout systems developed by Microsoft and Apple. Because digital screens and software-based layout engines require highly precise internal measurements, twips allowed consistent and resolution-independent positioning of graphical objects and text. Even when the actual pixel density of displays varied, twips provided a device-agnostic coordinate system. Twips remain particularly relevant in Microsoft technologies such as Visual Basic, Windows API interfaces, and the formatting of Office documents. Although ordinary users rarely encounter the term, twips form part of the invisible numerical infrastructure that ensures consistent layout across different computers, printers, and operating systems.
