1 MHz equals 1 microsecond. This means a frequency of 1 megahertz corresponds to a time period of 1 microsecond per cycle.
The conversion between megahertz and microseconds comes from the relationship between frequency and period. Frequency in MHz is the number of cycles per millionth of a second, so the period in microseconds is the inverse of frequency in MHz.

Conversion Formula
The conversion formula between megahertz (MHz) and microseconds (μs) is:
Period (μs) = 1 / Frequency (MHz)
This formula works because frequency is the number of cycles per second, but megahertz is million cycles per second. So the period, which is the duration of one cycle, is the reciprocal of frequency. Since 1 MHz equals 1 million cycles per second, the period in seconds is 1 divided by 1,000,000. Converting seconds to microseconds (1 second = 1,000,000 μs), the microseconds period is simply the inverse of MHz.
Example calculation for 1 MHz:
- Frequency = 1 MHz
- Period (seconds) = 1 / (1,000,000 Hz) = 1 x 10-6 seconds
- Convert to microseconds: 1 x 10-6 s × 1,000,000 μs/s = 1 μs
Conversion Example
- 5 MHz to microseconds:
- Frequency = 5 MHz
- Period = 1 / 5 = 0.2 μs (because 1 MHz = 1/μs)
- So, each cycle lasts 0.2 microseconds
- 0.25 MHz to microseconds:
- Frequency = 0.25 MHz
- Period = 1 / 0.25 = 4 μs
- Each cycle takes 4 microseconds to complete
- 10 MHz to microseconds:
- Frequency = 10 MHz
- Period = 1 / 10 = 0.1 μs
- The duration per cycle is 0.1 microseconds
- 0.5 MHz to microseconds:
- Frequency = 0.5 MHz
- Period = 1 / 0.5 = 2 μs
- Each cycle will take 2 microseconds

Conversion Definitions
MHz: MHz stands for megahertz, a unit of frequency equal to one million hertz or one million cycles per second. It is used to measure electromagnetic wave frequencies, processor clock speeds, and other periodic signals in electronics and communications.
Microseconds: A microsecond is a unit of time equal to one millionth (10-6) of a second. It is used to measure very short durations in scientific experiments, electronics timing, and signal processing where events happen at high speeds.
Conversion FAQs
Can frequency in MHz ever be negative?
No, frequency in MHz cannot be negative. Frequency represents the number of cycles per second, which is inherently a positive quantity. Negative values do not represent physical frequencies and thus cannot be converted to microseconds.
What happens if I try to convert 0 MHz to microseconds?
Converting 0 MHz to microseconds is undefined because the period is the inverse of frequency. Dividing 1 by zero frequency causes a mathematical error, so the period does not exist for 0 MHz.
Why does increasing MHz reduce the microseconds value?
Because frequency and period are inversely related, when MHz goes up, the duration of each cycle shortens. This means higher frequencies have shorter periods, so microseconds per cycle gets smaller as MHz increases.
Is this conversion useful in electronics timing?
Yes, converting MHz to microseconds helps in designing circuits and systems by understanding the timing intervals of signals. It allows engineers to set clock cycles, sample rates, and timing delays precisely.
Can this conversion be used for audio frequencies?
Audio frequencies are usually much lower than MHz, measured in Hz or kHz. While the formula applies, MHz to microseconds conversion is more relevant for radio frequencies and fast electronics, not typical audio ranges.
