Try this example →250 AU × 7,436,460,000 = 1,859,116,145,461 ch
Try this example →Astronomical unit (AU). An astronomical unit is the average distance from the Earth to the Sun, about 149.6 million kilometers.
Chain (ch). A chain is 66 feet (20.1168 m), a surveying unit; 80 chains make one mile.
There are 7,436,460,000 chains in one astronomical unit.
Multiply the number of astronomical units by 7,436,460,000. For example, 10 astronomical units equal 74,364,600,000 chains.
One chain equals 1.34473 × 10⁻¹⁰ astronomical units.
89,237,600,000 chains. Other common values: 5 astronomical units = 37,182,300,000 chains and 100 astronomical units = 743,646,458,184 chains.
