How to Convert Megahertz to Nanoseconds
Frequency and period are inversely related. The formula is: T = 1 / f, where T is the period and f is the frequency.
Conversion Steps
- The formula is:
Period = 1 / Frequency - For example, to convert 21000 MHz to ns:
- Convert to hertz: 21000 MHz = 21000 × 1.0e+6 = 2.1e+10 Hz
- Apply formula: T = 1 / 2.1e+10 Hz = 4.7619e-11 seconds
- Convert to nanoseconds: 4.7619e-11 s / 1.0e-9 = 2.1e+7 ns
Reverse Conversion
To convert nanoseconds back to megahertz, use f = 1 / T:
- 2.1e+7 ns → f = 1 / 4.7619e-11 s = 2.1e+10 Hz → 21000 MHz
