About Microsecond
One microsecond is one millionth of a second. Electronics and high-speed measurements use microseconds.
About Second
The second is the SI base unit of time (scientific definition via atomic clocks). This tool uses fixed-length seconds for conversion.
How to convert microseconds to seconds
1 microsecond is equal to 0.000001 second:
1 us = (0.000001 s ÷ 1 s) s = 0.000001 s
Each microsecond is defined as 0.000001 s and each second as 1 s, so one us equals 0.000001 ÷ 1 s = 0.000001 s.
Let t(us) be the numeric value of the same duration measured in Microsecond (us), and t(s) the value in Second (s). Then:
t(s) = t(us) × (0.000001 / 1)
Equivalently, divide by how many us fit into one s (seconds per s divided by seconds per us):
t(s) = t(us) ÷ 1000000
Or: second = microsecond ÷ 1000000
Examples
Example #1: Convert 20 us to second
20 us = 20 us × (0.000001/1) s = 0.00002 s
20 us = 20 us ÷ 1000000 = 0.00002 s
Example #2: Convert 50 us to second
50 us = 50 us × (0.000001/1) s = 0.00005 s
50 us = 50 us ÷ 1000000 = 0.00005 s
Summary
To convert Microsecond to Second, multiply the value in us by the ratio of seconds per us divided by seconds per s. Equivalently: value_s = value_us × (0.000001 / 1). Numerically, 1 us equals 0.000001 s.
Relationship context
You are converting between subsecond precision (milliseconds and smaller) (Microseconds) and hours, minutes, and seconds (Seconds). Very large and very small steps share the same second-based definitions here. The numeric factor is 1.000000e-6.
