20 microseconds equals 0.00002 seconds.
To convert microseconds to seconds, you divide the number of microseconds by 1,000,000 because there are one million microseconds in a second. So, 20 microseconds becomes 20 divided by 1,000,000, which results in 0.00002 seconds.

Conversion Formula
The conversion formula from microseconds to seconds is simple: seconds = microseconds ÷ 1,000,000.
Microseconds are a smaller unit than seconds, so to find out how many seconds a number of microseconds represent, you must divide by one million because 1 second contains 1,000,000 microseconds.
Step-by-step example for 20 microseconds:
- Start with 20 microseconds.
- Divide 20 by 1,000,000.
- 20 ÷ 1,000,000 = 0.00002 seconds.
- Therefore, 20 microseconds equals 0.00002 seconds.
Conversion Example
- Example: 150 microseconds to seconds
- Take 150 microseconds.
- Divide 150 by 1,000,000.
- 150 ÷ 1,000,000 = 0.00015 seconds.
- So, 150 microseconds equals 0.00015 seconds.
- Example: 5000 microseconds to seconds
- Begin with 5000 microseconds.
- Divide 5000 by 1,000,000.
- 5000 ÷ 1,000,000 = 0.005 seconds.
- Hence, 5000 microseconds is 0.005 seconds.
- Example: 0.75 microseconds to seconds
- Start with 0.75 microseconds.
- Divide 0.75 by 1,000,000.
- 0.75 ÷ 1,000,000 = 0.00000075 seconds.
- Therefore, 0.75 microseconds equals 0.00000075 seconds.
- Example: 1,000,000 microseconds to seconds
- Take 1,000,000 microseconds.
- Divide 1,000,000 by 1,000,000.
- 1,000,000 ÷ 1,000,000 = 1 second.
- So, 1,000,000 microseconds equals exactly 1 second.

Conversion Definitions
Microseconds: A microsecond is one millionth of a second, often used to measure very short time intervals. It is commonly used in electronics and computing contexts where precise timing below the millisecond scale is required. One microsecond equals 0.000001 seconds.
Seconds: The second is the base unit of time in the International System of Units (SI). It is used for measuring time intervals in everyday life and scientific contexts. One second is defined by the duration of 9,192,631,770 periods of radiation from a cesium atom.
Conversion FAQs
Can microseconds be negative in time measurements?
Yes, microseconds can be negative in some contexts, such as when measuring time differences relative to a reference point or in signal processing. Negative microseconds indicate a time before the reference event, not an absolute negative time.
Why is the conversion factor 1,000,000 when converting microseconds to seconds?
Because the prefix “micro” means one millionth, there are exactly 1,000,000 microseconds in one second. So to convert microseconds to seconds, you divide by 1,000,000, scaling the smaller unit into the larger base unit of time.
Is it accurate to round the converted seconds to 4 decimal places?
Rounding to four decimals can be enough for many practical uses, but since microseconds measure very small time spans, rounding can cause loss in precision. For precise measurements, more decimal places or scientific notation may be necessary.
How does this conversion apply in electronics?
In electronics, timing events often happen at microsecond scales. Converting microseconds to seconds allows engineers to compare and calculate delays and frequencies in standard units, which is necessary for designing circuits and systems correctly.
Can this conversion be reversed easily?
Yes, to convert seconds back to microseconds, multiply the seconds value by 1,000,000. This reverses the division process and gives the time in the smaller unit, microseconds.
