1 MHz equals 1 microsecond (µs) in period. This means that a frequency of 1 megahertz corresponds to a time interval of one microsecond between each cycle.
Since frequency and period are inverses, converting 1 MHz to microseconds involves taking the reciprocal of 1 million cycles per second, resulting in a period measured in microseconds.

Conversion Formula
The formula to convert frequency in megahertz (MHz) to period in microseconds (µs) is:
Period (µs) = 1 / (Frequency (MHz) × 1,000,000)
Because frequency measures how many cycles per second, and period measures the time duration of one cycle, they are inversely related. Since MHz means million cycles per second, multiply by 1,000,000 to convert MHz to Hz.
Example calculation for 1 MHz:
- Frequency = 1 MHz = 1,000,000 Hz
- Period = 1 / 1,000,000 seconds = 0.000001 seconds
- Convert seconds to microseconds: 0.000001 × 1,000,000 = 1 µs
Conversion Example
- 3 MHz to microseconds:
- Multiply: 3 × 1,000,000 = 3,000,000 Hz
- Calculate period: 1 / 3,000,000 = 0.0000003333 seconds
- Convert seconds to microseconds: 0.0000003333 × 1,000,000 = 0.3333 µs
- 0.5 MHz to microseconds:
- 0.5 × 1,000,000 = 500,000 Hz
- Period = 1 / 500,000 = 0.000002 seconds
- In microseconds: 0.000002 × 1,000,000 = 2 µs
- 10 MHz to microseconds:
- 10 × 1,000,000 = 10,000,000 Hz
- Period = 1 / 10,000,000 = 0.0000001 seconds
- Converted: 0.0000001 × 1,000,000 = 0.1 µs
- 0.25 MHz to microseconds:
- 0.25 × 1,000,000 = 250,000 Hz
- Period = 1 / 250,000 = 0.000004 seconds
- In microseconds: 0.000004 × 1,000,000 = 4 µs
- 5 MHz to microseconds:
- 5 × 1,000,000 = 5,000,000 Hz
- Period = 1 / 5,000,000 = 0.0000002 seconds
- Converted: 0.0000002 × 1,000,000 = 0.2 µs

Conversion Definitions
MHz: MHz stands for megahertz, a unit of frequency representing one million cycles per second. It describes how many times a periodic event repeats in one second, commonly used in radio frequencies, processors, and oscillators to indicate speed or signal rate.
Microseconds: A microsecond is a unit of time equal to one millionth of a second (10⁻⁶ seconds). It measures very brief time intervals, often used in electronics and communications to specify timing of high-speed processes or signal periods.
Conversion FAQs
Why can’t frequency be negative when converting to microseconds?
Frequency represents how many cycles occur per second, so it cannot be less than zero. A negative frequency has no physical meaning in this context, thus converting negative MHz to microseconds is invalid and not defined.
What happens if I enter zero MHz in the conversion?
Zero frequency means no cycles per second, which corresponds to an infinite period because the signal never repeats. Mathematically, dividing by zero is undefined, so the conversion does not produce a valid microsecond value.
Why is the period calculated by taking the reciprocal of frequency?
Frequency and period are inverses because frequency counts cycles per time unit, while period measures time per cycle. Taking the reciprocal switches between these perspectives, giving the duration of each cycle from the number of cycles per second.
How precise is the microsecond value when converting from MHz?
The precision depends on input frequency accuracy and rounding. Since the calculation involves dividing 1 by frequency in hertz, small changes in frequency can affect period especially at higher values, but four decimal places usually suffice for general applications.
Can this conversion be used for frequencies higher than MHz?
Yes, you can convert any frequency value by adjusting units correctly. For GHz or kHz, convert to Hz first by multiplying appropriately, then take reciprocal. The formula remains essentially the same with proper unit conversion.
