GET /api/convert/hertz-to-gigahertzConvert hertz to gigahertz (frequency). Pass ?value=N.
1 hertz = 1e-9 gigahertz. To convert, multiply the number of hertz by 1e-9. The reverse direction is gigahertz → hertz.
| hertz | gigahertz |
|---|---|
| 1 hertz | 1e-9 gigahertz |
| 2 hertz | 2e-9 gigahertz |
| 5 hertz | 5e-9 gigahertz |
| 10 hertz | 1e-8 gigahertz |
| 25 hertz | 2.5e-8 gigahertz |
| 100 hertz | 1e-7 gigahertz |
| 1000 hertz | 0.000001 gigahertz |

This is a pure-CPU tool, so an agent without a wallet can pay with proof-of-work instead of USDC: fetch a challenge, solve it (16 leading zero bits), and resend with the X-Pow-Solution header.
