About Converting Exahertz to Petahertz
Exahertz and Petahertz both describe how fast something cycles or rotates, and the conversion is a routine part of reading a car tachometer or motor spec sheet against a scientific frequency figure. Specifically: Exahertz is 1000000000000000000 hertz units, and petahertz is 1000000000000000 hertz units.
Formula
petahertz = exahertz × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 exahertz equals 1e+18 base units, and 1 petahertz equals 1e+15 base units, so dividing one by the other gives the direct exahertz-to-petahertz factor of 1000.
Simple example
1 EHz × 1000 = 1,000 PHz
1 exahertz = 1,000 petahertz.
Real-world example
1,000 EHz × 1000 = 1,000,000 PHz
1,000 exahertz = 1,000,000 petahertz.
Conversion table
| Exahertz (EHz) | Petahertz (PHz) |
|---|---|
| 60 EHz | 60,000 PHz |
| 600 EHz | 600,000 PHz |
| 1,000 EHz | 1,000,000 PHz |
| 3,000 EHz | 3,000,000 PHz |
| 6,000 EHz | 6,000,000 PHz |
| 10,000 EHz | 10,000,000 PHz |
Reverse conversion: Petahertz to Exahertz
1 PHz × 0.001 = 0.001 EHz
1 petahertz = 0.001 exahertz.
exahertz = petahertz × 0.001

Frequently asked questions
How many petahertz are in 1 exahertz?
1 exahertz equals 1,000 petahertz, using the exact defined conversion factor rather than an estimate.
How do I convert exahertz to petahertz?
Multiply the exahertz value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert petahertz back to exahertz?
Use the reverse factor: 1 petahertz equals 0.001 exahertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a exahertz?
Exahertz (EHz) is a unit of frequency.
What is a petahertz?
Petahertz (PHz) is a unit of frequency.
Is the exahertz to petahertz conversion exact?
Yes. Both exahertz and petahertz are defined by fixed standards rather than physical artifacts, so the factor of 1000 used above is exact to as many digits as you choose to display.
