About these units
Gigameter (Gm)
A gigameter, one billion meters (10⁹ m), moves firmly into interplanetary territory. Astronomers use gigameters to express distances within the solar system, such as the average separation between planets or the orbital paths of spacecraft. For example, the Earth–Moon distance (~384,000 km) can be expressed as 0.384 Gm, and distances to nearby planets often fall in the range of tens or hundreds of gigameters depending on orbital positions. The gigameter is particularly useful in scientific models where distances are massive but still fall short of interstellar scales. It reduces the need for unwieldy scientific notation and gives researchers a manageable unit for calculations involving gravitational fields, orbital dynamics, and space mission planning.
Pica (pica)
A pica is another typographic unit, equal to 12 points, or 1/6 of an inch, making it larger and more suited to structural layout than to fine detail. Picas are commonly used to measure text blocks, column widths, margins, and line lengths in print and digital page design. The pica originated alongside the point in printing traditions stretching back to the 18th and 19th centuries. It offered a convenient intermediate scale—small enough for precise adjustments but large enough for practical page design. When newspapers became widespread, picas helped designers rapidly calculate column grids and organize dense printed pages. Even as publishing tools evolved into software like Adobe InDesign and LaTeX, picas remain deeply integrated into the workflow of book designers, typographers, and professional printers. They are part of a system that allows page elements to be arranged with precision, ensuring that every visual aspect of a document aligns harmoniously.
