1 MHz equals 1 microsecond (µs) in terms of period. This means a frequency of 1 megahertz corresponds to a time interval of 1 microsecond per cycle.
The conversion from megahertz (MHz) to microseconds (µs) involves finding the period, which is the inverse of frequency. Since 1 MHz means 1 million cycles per second, each cycle lasts one millionth of a second, or 1 microsecond.

Conversion Formula
To convert megahertz to microseconds, use the formula:
Period (µs) = 1 / Frequency (MHz)
Frequency is the number of cycles per second, measured in megahertz, where 1 MHz = 1,000,000 Hz. The period is the time duration of one cycle, which is the reciprocal of frequency.
Since 1 MHz = 1,000,000 cycles/second, the period in seconds is:
- Period (seconds) = 1 / (1,000,000) = 0.000001 seconds
- Convert seconds to microseconds: 0.000001 s × 1,000,000 = 1 µs
So, 1 MHz corresponds to a period of 1 microsecond per cycle.
Conversion Example
- Example 1: 5 MHz to microseconds
- Start with frequency: 5 MHz
- Calculate period: 1 / 5 = 0.2 microseconds
- This means each cycle lasts 0.2 µs.
- Example 2: 0.25 MHz to microseconds
- Frequency is 0.25 MHz
- Period = 1 / 0.25 = 4 microseconds
- Each cycle takes 4 µs.
- Example 3: 12.5 MHz to microseconds
- Frequency: 12.5 MHz
- Period = 1 / 12.5 = 0.08 microseconds
- Each cycle duration is 0.08 µs.
- Example 4: 0.1 MHz to microseconds
- Frequency: 0.1 MHz
- Period = 1 / 0.1 = 10 microseconds
- Each cycle lasts 10 µs.

Conversion Definitions
MHz: Megahertz, abbreviated MHz, is a unit of frequency equal to one million cycles per second. It measure how many million events or oscillations occur every second in a system, often used to describe radio waves, processor speeds, and signal frequencies in electronics.
Microseconds: A microsecond (µs) is a unit of time equal to one millionth of a second (10⁻⁶ seconds). It measures very short durations commonly used in electronics and communications to describe timing intervals, pulse durations, or signal periods at high frequencies.
Conversion FAQs
Why is the period the inverse of frequency when converting MHz to microseconds?
The period of a waveform is the time taken to complete one cycle, which is the reciprocal of frequency. Since frequency tells how many cycles occur per second, dividing 1 by frequency gives the length of one cycle in seconds or microseconds.
Can frequency values less than 1 MHz be converted the same way?
Yes, frequencies below 1 MHz are converted using the same formula. For example, 0.5 MHz corresponds to a period of 2 microseconds. The formula 1/frequency holds true for any positive frequency value.
What happens if frequency is zero or negative when converting to microseconds?
A frequency of zero means no cycles per second, so the period is infinite or undefined. Negative frequencies do not have physical meaning in this context, and the formula cannot be applied correctly for negative values.
Is there a difference when converting MHz to microseconds if the signal is not a perfect sine wave?
The formula calculates the period based on frequency alone, regardless the waveform shape. For non-sine waves, the fundamental frequency’s period still equals 1/frequency, but signal characteristics like harmonics may affect timing in complex ways.
How precise is the conversion from MHz to microseconds?
The conversion is mathematically exact when using the reciprocal formula, but real-world measurements may include small errors due to instrument precision, environmental factors, or signal distortions.
