9 microseconds equals 0.000009 seconds.
To convert microseconds to seconds, you divide the number of microseconds by 1,000,000 because one second contains one million microseconds. So, 9 microseconds is 9 divided by 1,000,000, which results in 0.000009 seconds.

Conversion Formula
The formula to convert microseconds (µs) to seconds (s) is:
seconds = microseconds ÷ 1,000,000
This works because one second contains exactly 1,000,000 microseconds. By dividing the number of microseconds by one million, you get the equivalent value in seconds.
Example calculation for 9 microseconds:
- Start with 9 microseconds
- Divide 9 by 1,000,000
- 9 ÷ 1,000,000 = 0.000009 seconds
Conversion Example
- Convert 15 microseconds to seconds:
- Take 15 microseconds
- Divide by 1,000,000
- 15 ÷ 1,000,000 = 0.000015 seconds
- Convert 250 microseconds to seconds:
- Start with 250 microseconds
- Divide 250 by 1,000,000
- 250 ÷ 1,000,000 = 0.00025 seconds
- Convert 1,000 microseconds to seconds:
- Begin with 1,000 microseconds
- Divide by 1,000,000
- 1,000 ÷ 1,000,000 = 0.001 seconds
- Convert 500,000 microseconds to seconds:
- Value is 500,000 microseconds
- Divide 500,000 by 1,000,000
- 500,000 ÷ 1,000,000 = 0.5 seconds

Conversion Definitions
Microsecond: A microsecond is a unit of time equal to one millionth of a second (1/1,000,000 seconds). It measures very short time intervals, often used in electronics, computing, and physics where extremely rapid events happen within fractions of a second.
Second: The second is the SI base unit of time, defined as exactly 9,192,631,770 periods of radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom. It is the standard unit for measuring time intervals in everyday life and science.
Conversion FAQs
Why do we divide microseconds by 1,000,000 to get seconds?
Because one second contains exactly one million microseconds, dividing the microsecond value by 1,000,000 converts it correctly into seconds. This scaling aligns the smaller unit (microsecond) to the larger unit (second).
Can microseconds be larger than a second?
No, microseconds are always smaller than a second, but you can have a large count of microseconds that add up to multiple seconds. For example, 1,500,000 microseconds equals 1.5 seconds.
Is it possible to convert microseconds to minutes or hours?
Yes, by first converting microseconds to seconds, then dividing by 60 for minutes or 3600 for hours. For instance, 3,600,000,000 microseconds is 3,600 seconds, which is 1 hour.
How accurate is converting microseconds to seconds using this method?
The conversion by dividing by one million is exact because the units are defined based on powers of ten. Any error would come from rounding when displaying decimal places, not the conversion itself.
Why do some calculators show scientific notation for microsecond to second conversions?
Because microseconds are very small units compared to seconds, their converted values tend to be very small decimal numbers. Scientific notation makes it easier to read and understand these tiny values.
