The exact conversion ratio — 0.000304617 — anchored to SI definitions, not rounded

1. 01Look up the SI factors: 1 square degree = 0.00030461742 base units, 1 steradian = 1 base units.
2. 02Divide to get the conversion ratio: 0.00030461742 / 1 = 0.000304617.
3. 03Multiply by the quantity: 5 × 0.000304617 = 0.00152309.
4. 04So 5 square degrees = 0.00152309 steradians.
