Category: Unit Converters
Formula: Ω = 2π(1 − cosθ)
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Half-cone angle | th | deg | 10 |
Result with the default inputs
- Solid angle: 0.0955 sr
- msr: 95.4557 msr
- Full cone: 20 °
Open it with your own values: put each input in the address as a parameter, for example /calculators/solid-angle-cone?th=10. A unit other than the listed one goes in <parameter>_unit.
