100 microseconds equals 10,000 Hz.
Converting microseconds to hertz involves finding how many cycles occur per second if each cycle lasts the given microseconds. Since 1 second has 1,000,000 microseconds, dividing that by the microseconds value gives frequency in hertz.

Conversion Formula
To convert microseconds (µs) to hertz (Hz), use the formula:
Frequency (Hz) = 1,000,000 ÷ Time (µs)
This formula works because frequency is the number of cycles per second, and one cycle duration is given in microseconds. Since 1 second equals 1,000,000 microseconds, dividing 1,000,000 by the cycle time in microseconds gives how many cycles happen each second.
Example:
- Given time = 100 µs
- Frequency = 1,000,000 ÷ 100 = 10,000 Hz
Conversion Example
- For 200 microseconds:
- Start with 1,000,000 microseconds in a second
- Divide 1,000,000 by 200 to get frequency
- 1,000,000 ÷ 200 = 5,000 Hz
- For 50 microseconds:
- Divide 1,000,000 by 50
- 1,000,000 ÷ 50 = 20,000 Hz
- For 400 microseconds:
- Calculate 1,000,000 divided by 400
- Result is 2,500 Hz
- For 125 microseconds:
- Calculate 1,000,000 ÷ 125
- Result is 8,000 Hz
- For 80 microseconds:
- Divide 1,000,000 by 80
- Resulting frequency is 12,500 Hz

Conversion Definitions
Microseconds: A microsecond is one millionth of a second, written as 1 µs = 0.000001 seconds. It is used to measure extremely short time intervals, common in electronics and signal processing where very fast events happen within tiny fractions of a second.
Hz (Hertz): Hertz is the unit of frequency, representing the number of cycles or events per second. One hertz equals one cycle per second. It is widely used in physics, engineering, and audio to describe periodic phenomena like waves, oscillations, or clock signals.
Conversion FAQs
Why does dividing one million by microseconds give frequency in hertz?
Because frequency is how many cycles happen in one second, and microseconds measure the duration of one cycle, dividing the total microseconds in a second (1,000,000) by the cycle time gives number of cycles per second, which is frequency in Hz.
Can this conversion be used for any signal period in microseconds?
Yes, any cycle duration expressed in microseconds can be converted to frequency by this method. However, if the signal period includes delays or is not constant, the calculated frequency might not be accurate for those cases.
What if the microseconds value is zero or very small?
If the microseconds value is zero, frequency calculation is impossible since division by zero is undefined. Very small values lead to very high frequency results, which might be beyond the practical limits of most devices or measurements.
Is this conversion valid for non-periodic signals?
No, this conversion assumes the time represents a regular cycle period. For non-periodic signals or irregular intervals, frequency cannot be determined meaningfully from a single microsecond value.
How precise is frequency from microseconds when measuring real signals?
Precision depends on the accuracy of the microseconds measurement. Small errors in time measurement can cause noticeable differences in calculated frequency, especially at high frequencies where cycles are very short.
