About Converting Petahertz to Megahertz
Petahertz and Megahertz 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: Petahertz is 1000000000000000 hertz units, and megahertz is 1000000 hertz units.
Formula
megahertz = petahertz × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 petahertz equals 1e+15 base units, and 1 megahertz equals 1000000 base units, so dividing one by the other gives the direct petahertz-to-megahertz factor of 1000000000.
Simple example
1 PHz × 1000000000 = 1,000,000,000 MHz
1 petahertz = 1,000,000,000 megahertz.
Real-world example
1,000 PHz × 1000000000 = 1e+12 MHz
1,000 petahertz = 1e+12 megahertz.

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

Frequently asked questions
How many megahertz are in 1 petahertz?
1 petahertz equals 1,000,000,000 megahertz, using the exact defined conversion factor rather than an estimate.
How do I convert petahertz to megahertz?
Multiply the petahertz value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert megahertz back to petahertz?
Use the reverse factor: 1 megahertz equals 1e-9 petahertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a petahertz?
Petahertz (PHz) is a unit of frequency.
What is a megahertz?
Megahertz (MHz) is a unit of frequency.
Is the petahertz to megahertz conversion exact?
Yes. Both petahertz and megahertz are defined by fixed standards rather than physical artifacts, so the factor of 1000000000 used above is exact to as many digits as you choose to display.
