1 microsecond equals 0.000001 seconds.
To convert microseconds to seconds, you divide the number of microseconds by 1,000,000 because there are one million microseconds in a single second.

Conversion Formula
The formula used to convert microseconds (µs) to seconds (s) is:
seconds = microseconds ÷ 1,000,000
This formula works because 1 second contains exactly 1,000,000 microseconds. When you want to find how many seconds correspond to a given number of microseconds, you divide that number by one million.
Example calculation:
- Given: 5 microseconds
- Calculate seconds: 5 ÷ 1,000,000 = 0.000005 seconds
Conversion Example
- Convert 10 microseconds to seconds:
- Step 1: Identify the value in microseconds (10)
- Step 2: Divide by 1,000,000 → 10 ÷ 1,000,000
- Step 3: Calculate the result → 0.00001 seconds
- Convert 250 microseconds to seconds:
- Step 1: Value is 250 µs
- Step 2: 250 ÷ 1,000,000
- Step 3: Result is 0.00025 seconds
- Convert 0.5 microseconds to seconds:
- Step 1: Value is 0.5 µs
- Step 2: 0.5 ÷ 1,000,000
- Step 3: Result is 0.0000005 seconds
- Convert 1000 microseconds to seconds:
- Step 1: Value is 1000 µs
- Step 2: 1000 ÷ 1,000,000
- Step 3: Result is 0.001 seconds

Conversion Definitions
Microsecond: A microsecond is a unit of time equal to one millionth (1/1,000,000) of a second. It is used to measure very short durations, such as in electronics, computing, and physics, when high precision timing is needed for processes or events.
Second: The second is the base unit of time in the International System of Units (SI). Defined by the vibrations of cesium atoms, one second represents the duration of 9,192,631,770 periods of radiation from the cesium-133 atom, providing an exact and reproducible standard for time measurement.
Conversion FAQs
Why is the number one million used in converting microseconds to seconds?
One million is used because a microsecond is defined as one millionth of a second. This means that to convert microseconds into seconds, you divide by 1,000,000. The prefix “micro-” in the metric system denotes a factor of 10⁻⁶, or 0.000001.
Can microseconds be larger than a second?
No, microseconds cannot be larger than a second, since they represent a division of one second. If a measurement is larger than one second, it would be expressed in seconds or larger units like minutes or hours, not microseconds.
How accurate is converting microseconds to seconds using decimal division?
Converting microseconds to seconds by dividing by one million is accurate and exact in mathematics. However, practical accuracy may depend on the precision of the measurement instruments or the number of decimal places used in the result.
Is there a shortcut to convert microseconds to milliseconds before seconds?
Yes, since 1 millisecond equals 1,000 microseconds, you can first convert microseconds to milliseconds by dividing by 1,000, and then milliseconds to seconds by dividing by 1,000 again. But directly dividing microseconds by 1,000,000 is faster and simpler.
Why do some devices measure time in microseconds instead of seconds?
Devices that require very fast timing, like processors or high-speed electronics, measure time in microseconds because seconds are too large to capture the tiny intervals accurately. Using microseconds allows for precise control and measurement of very short time spans.
