### FAQ about Petahertz to Millihertz Conversion

1 petahertz (PHz) is equal to 1.0E+18 millihertz (mHz).

1PHz = 1.0E+18mHz

The frequency wavelength λ in millihertz (mHz) is equal to the frequency wavelength λ in petahertz (PHz) times 1.0E+18, that conversion formula:

λ(mHz) = λ(PHz) × 1.0E+18

One Petahertz is equal to 1.0E+18 Millihertz:

1PHz = 1PHz × 1.0E+18 = 1.0E+18mHz

1000 Millihertz is equal to 0 Petahertz:

1000mHz = 1000mHz / 1000000000000000000 = 0PHz

λ(mHz) = 5(PHz) × 1.0E+18 = 5.0E+18mHz
