A "twip" is a unit of measurement used in desktop publishing and computer graphics, especially in the context of Microsoft Windows. The term "twip" is an abbreviation for "twentieth of a point," and it is used to define very small distances and sizes.
In the twip system:
1 twip is equal to 1/20th of a point. 1 point (abbreviated as "pt") is equal to approximately 20 twips.
Because a point is roughly 1/72nd of an inch, 1 twip is approximately 1/1440th of an inch (or about 1/567 millimeters).
Twips are used in various applications, including word processing, graphics design, and layout software. They are particularly valuable for precise positioning and sizing of elements on a computer screen or when preparing documents for printing. The twip system is commonly used in Microsoft Windows-based applications and the Windows Graphics Device Interface (GDI).
For example, in Microsoft Word, you can set paragraph spacing or element positioning in twips to achieve fine control over the layout of your documents.
A "hand" is a unit of measurement commonly used in the context of measuring the height of horses. In the United States and some other English-speaking countries, a hand is defined as exactly 4 inches or 10.16 centimeters.
Horses are typically measured in hands from the ground to the highest point of their withers (the ridge between the shoulder blades). This measurement is a convenient way to describe a horse's height without relying on feet and inches or meters.
For example, a horse that measures 15.2 hands is 15 hands and 2 inches tall. Horses can vary in height, and the hand system provides a standardized way to communicate a horse's size, which is particularly important in horse racing, equestrian sports, and the horse industry in general.
