Those two units are completely unrelated. Meter is a measure of length, Hertz is a unit of frequency (reciprocal of seconds).
1,000 KHz = 1 MHz
It seems you are talking about radio waves. The wavelength (40 m) multiplied by the frequency (7 million / second) must equal the speed of light (300 million meters/second). It seems that in this example numbers, either the wavelength or the frequency, or both, are not expressed with a great accuracy. For example, if 40 meters is exact, the frequency would be close to 7.5 MHz.
400-470 mhz = -70
5 MHz = 1 second divided by 5.000.000 4.77 MHz = 1 second divided by 4.770.000
The period of 1 MHz is 1 microsecond. The waveform is irrelevant.
500m Commercial AM broadcast in the USA takes place in the band of 0.55 to 1.7 MHz, corresponding to wavelengths from 176.3 to 545.1 meters.
20 MHz
1 MBPs how many MHZ
100 MHz (near the middle of the commercial FM broadcast band)
1900 MHz
2700 MHz
"Meters" is not frequency. It's wavelength. If you know the wavelength in meters, divide 300 by it, and the result is the frequency in MHz. If you know the frequency in MHz, divide 300 by it, and the result is the wavelength in meters.
Divide 300 by 2,500,000,000 to get a wavelength of 0.00000015 metres. Wavelength metres = 300 / f(mHz) = 300 / 2500 mHz = 0.12 metres. (2.5 gHz = 2500 mHz)
The frequency can't be 30 Mhz 30 Mhz is a ham radio frequency but to calculate the wavelength, devide 300 by the frequency in Mhz that will give you 10 meters (300/ƒ)
As many as you like, watts and MHz have no equivalence because watts measure power while MHz measure frequency.
There is about 1.04 GHz in 1066 MHz.
Just divide the speed of light (300 million meters/second) by the frequency, remembering that MHz means "millions of hertz".
