Try this example →250 AU × 7,436,450,000 = 1,859,112,427,568 chUS
Try this example →Astronomical unit (AU). An astronomical unit is the average distance from the Earth to the Sun, about 149.6 million kilometers.
US survey chain (chUS). The US survey chain is 66 US survey feet, about 20.1168 m.
There are 7,436,450,000 US survey chains in one astronomical unit.
Multiply the number of astronomical units by 7,436,450,000. For example, 10 astronomical units equal 74,364,500,000 US survey chains.
One US survey chain equals 1.34473 × 10⁻¹⁰ astronomical units.
89,237,400,000 US survey chains. Other common values: 5 astronomical units = 37,182,200,000 US survey chains and 100 astronomical units = 743,644,971,027 US survey chains.
