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.
The nautical league in the United Kingdom is a unit of nautical measurement that is traditionally defined as three nautical miles. A nautical mile, also known as a sea mile, is a unit of distance used in navigation and marine contexts. It is based on the circumference of the Earth and is approximately equal to one minute of latitude along a meridian.
In the United Kingdom and many other maritime nations, a nautical league is considered to be equal to three nautical miles, which is roughly equivalent to 5.556 kilometers or 3.452 statute miles (land miles). This measurement is used for maritime and navigational purposes, especially for calculating distances at sea.
It's worth noting that the use of traditional nautical measurements like leagues has largely been replaced by more standardized and precise modern navigation methods that rely on nautical miles and other internationally recognized units. Nonetheless, these older units of measurement may still be referenced in historical documents or traditional maritime contexts.
