About Converting Megahertz to Petahertz
Megahertz 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: Megahertz is 1000000 hertz units, and petahertz is 1000000000000000 hertz units.
Formula
petahertz = megahertz × 1e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 megahertz equals 1000000 base units, and 1 petahertz equals 1e+15 base units, so dividing one by the other gives the direct megahertz-to-petahertz factor of 1e-9.
Simple example
1 MHz × 1e-9 = 1e-9 PHz
1 megahertz = 1e-9 petahertz.
Real-world example
1,000 MHz × 1e-9 = 0.000001 PHz
1,000 megahertz = 0.000001 petahertz.

Reverse conversion: Petahertz to Megahertz
1e-9 PHz × 1000000000 = 1 MHz
1e-9 petahertz = 1 megahertz.
megahertz = petahertz × 1000000000

Frequently asked questions
How many petahertz are in 1 megahertz?
1 megahertz equals 1e-9 petahertz, using the exact defined conversion factor rather than an estimate.
How do I convert megahertz to petahertz?
Multiply the megahertz value by 1e-9. The converter above does this instantly to whatever precision you set.
How do I convert petahertz back to megahertz?
Use the reverse factor: 1 petahertz equals 1,000,000,000 megahertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a megahertz?
Megahertz (MHz) is a unit of frequency.
What is a petahertz?
Petahertz (PHz) is a unit of frequency.
Is the megahertz to petahertz conversion exact?
Yes. Both megahertz and petahertz are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 used above is exact to as many digits as you choose to display.
