§02The Formula

How it’s calculated

1 milliradian = 206.265 arcseconds → value_in_arcsecond = value_in_milliradian × 206.265

Where

value_in_milliradian
The number of milliradians you start with (the value you enter above)
value_in_arcsecond
The equivalent number of arcseconds (the result)
factor
The exact conversion ratio — 206.265 — anchored to SI definitions, not rounded
§03Practical Example

Step-by-step walkthrough

Scenario

Convert 5 milliradians to arcseconds.

  1. 01Look up the SI factors: 1 milliradian = 0.001 base units, 1 arcsecond = 0.00000484813681109536 base units.
  2. 02Divide to get the conversion ratio: 0.001 / 0.00000484813681109536 = 206.265.
  3. 03Multiply by the quantity: 5 × 206.265 = 1031.32.
  4. 04So 5 milliradians = 1031.32 arcseconds.
