| 1,000,000 chUS | 0.000134473 AU |
25 chUS × 1.34473 × 10⁻¹⁰ = 3.36182 × 10⁻⁹ AU
Try this example →250 chUS × 1.34473 × 10⁻¹⁰ = 3.36182 × 10⁻⁸ AU
Try this example →US survey chain (chUS). The US survey chain is 66 US survey feet, about 20.1168 m.
Astronomical unit (AU). An astronomical unit is the average distance from the Earth to the Sun, about 149.6 million kilometers.
There are 1.34473 × 10⁻¹⁰ astronomical units in one US survey chain.
Multiply the number of US survey chains by 1.34473 × 10⁻¹⁰. For example, 10 US survey chains equal 1.34473 × 10⁻⁹ astronomical units.
One astronomical unit equals 7,436,450,000 US survey chains.
1.34473 × 10⁻⁷ astronomical units. Other common values: 100 US survey chains = 1.34473 × 10⁻⁸ astronomical units and 10,000 US survey chains = 1.34473 × 10⁻⁶ astronomical units.
