value_in_degree
The equivalent number of degrees (the result)
factor
The exact conversion ratio — 0.000277778 — anchored to SI definitions, not rounded
§03Practical Example

Step-by-step walkthrough

Scenario

Convert 5 arcseconds to degrees.

  1. 01Look up the SI factors: 1 arcsecond = 0.00000484813681109536 base units, 1 degree = 0.017453292519943295 base units.
  2. 02Divide to get the conversion ratio: 0.00000484813681109536 / 0.017453292519943295 = 0.000277778.
  3. 03Multiply by the quantity: 5 × 0.000277778 = 0.00138889.
  4. 04So 5 arcseconds = 0.00138889 degrees.
