20 Hz corresponds to 50000 microseconds. This means one cycle at 20 Hz takes 50000 microseconds to complete.
The conversion from hertz to microseconds involves finding the period of one cycle in seconds and then converting that to microseconds. Since hertz measures cycles per second, the period is the inverse of the frequency.

Conversion Formula
The formula to convert frequency in hertz to time period in microseconds is:
Period (μs) = (1 / Frequency (Hz)) × 1,000,000
This formula works because frequency is the number of cycles per second. The period is the duration of one cycle, which is the reciprocal of frequency. Multiplying by 1,000,000 converts seconds to microseconds.
Example calculation for 20 Hz:
- Calculate the period in seconds: 1 ÷ 20 = 0.05 seconds
- Convert to microseconds: 0.05 × 1,000,000 = 50,000 microseconds
Conversion Example
- Convert 5 Hz to microseconds:
- 1 ÷ 5 = 0.2 seconds
- 0.2 × 1,000,000 = 200,000 microseconds
- Convert 50 Hz to microseconds:
- 1 ÷ 50 = 0.02 seconds
- 0.02 × 1,000,000 = 20,000 microseconds
- Convert 0.1 Hz to microseconds:
- 1 ÷ 0.1 = 10 seconds
- 10 × 1,000,000 = 10,000,000 microseconds
- Convert 100 Hz to microseconds:
- 1 ÷ 100 = 0.01 seconds
- 0.01 × 1,000,000 = 10,000 microseconds
- Convert 0.5 Hz to microseconds:
- 1 ÷ 0.5 = 2 seconds
- 2 × 1,000,000 = 2,000,000 microseconds

Conversion Definitions
Hz (Hertz): Hertz is a unit measuring frequency, representing the number of cycles or events per second. It’s used to quantify how often something repeats, such as waves, vibrations, or signals, with one hertz meaning one cycle every second.
Microseconds: A microsecond is a unit of time equal to one millionth of a second (1/1,000,000). It’s used to measure very short time intervals, often in electronics, physics, or communications where precise timing is necessary.
Conversion FAQs
Why can’t frequency be negative when converting to microseconds?
Frequency represents how many cycles occur every second, so it can’t be negative. A negative value would imply cycles happening backwards in time, which is physically meaningless. Therefore, conversion to microseconds requires positive frequency values.
What happens if frequency is zero in the conversion formula?
Dividing by zero is undefined, so if frequency is zero, the period becomes infinite. This means no cycles occur per second, so no time period per cycle can be calculated, making the conversion impossible.
Can this conversion be used for audio frequencies like 20 Hz?
Yes, this conversion helps find the duration of one cycle at audio frequencies. For example, a 20 Hz wave has a period of 50,000 microseconds, which is useful in audio processing and signal timing calculations.
Why multiply by 1,000,000 in the formula?
Because frequency is in hertz (cycles per second), the inverse gives seconds per cycle. Multiplying by 1,000,000 converts seconds into microseconds, which are smaller, more precise time units.
Is the result always exact when converting from Hz to microseconds?
The result depends on the precision of the input and rounding in calculations. Sometimes the period won’t be a whole number, so decimals or rounding errors occur, but the formula provides a very close approximation.
