The Chain (Gunter's chain) was fundamental in surveying the American frontier. Measuring 66 feet (4 rods), it's the length of a cricket pitch. Ten square chains make an acre. Modern surveyors still reference chains in legal descriptions, and the unit remains visible in rural road layouts across the US. Interplanetary distances (Jupiter is 588 Tm from the Sun). Mostly for astrophysics research.
To convert between Chain (ch) and Terameter (Tm), use the following formulas:
1 Chain (ch) = 2.0116800000000002e-11 Terameter (Tm)
1 Terameter (Tm) = 49709695378.98672 Chain (ch)
1 ch = 1 * 2.0116800000000002e-11 Tm = 2.0116800000000002e-11 Tm
5 ch = 5 * 2.0116800000000002e-11 Tm = 1.0058400000000001e-10 Tm
10 ch = 10 * 2.0116800000000002e-11 Tm = 2.0116800000000002e-10 Tm
20 ch = 20 * 2.0116800000000002e-11 Tm = 4.0233600000000005e-10 Tm
50 ch = 50 * 2.0116800000000002e-11 Tm = 1.0058400000000001e-9 Tm
100 ch = 100 * 2.0116800000000002e-11 Tm = 2.0116800000000002e-9 Tm
