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 (ch)
A chain is equal to 66 feet or 4 rods, and it was standardized by surveyor Edmund Gunter in the 17th century. "Gunter's chain," consisting of 100 metal links, became the backbone of land surveying in the English-speaking world for centuries. Its convenience stems from simple arithmetic: 10 square chains make an acre, making land area calculations straightforward. Railroads, farmland, and city parcels across the United States and the Commonwealth nations were once laid out using chains, so the unit appears in countless historical records. Even today, some legal property descriptions still reference chain-based measurements, making the unit relevant for modern surveyors who interpret old maps. Although high-precision digital equipment has replaced physical chains, the unit's structural role in land division ensures its lasting importance.
