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.
Chain (US Survey) (ch (US))
The US Survey Chain is defined as 66 US Survey Feet (~20.1168 meters), aligning with the historic Gunter's chain but adapted to the US survey foot. It is used primarily in cadastral surveys, property delineation, and historical land records. Surveyors employ the chain for practical measurements of fields, lots, and infrastructure layouts. The unit's subdivision into 100 links simplifies area calculation, as 10 square chains equal one acre, maintaining continuity with older surveying systems. Even today, engineers and surveyors working with legacy data encounter the US survey chain in historical deeds, maps, and legal descriptions. Its precision ensures consistency when reconciling pre-modern measurements with modern coordinates.
