20 microseconds is equal to 0.02 milliseconds.
Microseconds and milliseconds are units of time measurement, where 1 millisecond equals 1,000 microseconds. To convert 20 microseconds to milliseconds, you divide 20 by 1,000, resulting in 0.02 milliseconds.

Conversion Formula
The formula to convert microseconds to milliseconds is:
Milliseconds = Microseconds ÷ 1000
Since 1 millisecond equals 1,000 microseconds, dividing the microsecond value by 1000 gives the equivalent time in milliseconds. This works because milliseconds are larger units, so it takes 1000 microseconds to make 1 millisecond.
For example, converting 20 microseconds:
- Start with 20 microseconds.
- Divide 20 by 1000.
- Result: 20 ÷ 1000 = 0.02 milliseconds.
Conversion Example
- Convert 500 microseconds to milliseconds:
- Take 500 microseconds.
- Divide by 1000: 500 ÷ 1000 = 0.5 milliseconds.
- Therefore, 500 microseconds equals 0.5 milliseconds.
- Convert 1250 microseconds to milliseconds:
- Start with 1250 microseconds.
- Divide 1250 by 1000: 1250 ÷ 1000 = 1.25 milliseconds.
- So, 1250 microseconds is 1.25 milliseconds.
- Convert 0 microseconds to milliseconds:
- 0 microseconds divided by 1000 is 0.
- Thus, 0 microseconds equals 0 milliseconds.
- Convert 750 microseconds to milliseconds:
- 750 ÷ 1000 = 0.75 milliseconds.
- Hence, 750 microseconds equals 0.75 milliseconds.

Conversion Definitions
Microseconds: A microsecond is a unit of time equal to one millionth of a second (0.000001 seconds). It’s used to measure very short durations in electronics, computing, and physics where timing precision on the scale of millionths of seconds matters. The symbol for microseconds is µs.
Milliseconds: A millisecond represents one thousandth of a second (0.001 seconds). It is used in timing events that are shorter than a second but longer than microseconds. Milliseconds are common in measuring computer response times, audio delays, and other short intervals. The symbol for milliseconds is ms.
Conversion FAQs
Does converting microseconds to milliseconds affect accuracy?
Converting microseconds to milliseconds involves dividing by 1000, which can cause loss of precision if the values are very small or decimals are truncated. To keep accuracy, use decimal places when showing results, especially in scientific or technical contexts where exact timing is crucial.
Can microseconds have negative values?
Yes, negative microseconds can appear in contexts like time differences or offsets relative to a reference point, such as before a trigger event. Though unusual in everyday timing, negative values are valid in certain measurement systems or programming environments.
Why is the conversion factor between microseconds and milliseconds 1000?
Because one millisecond contains exactly 1000 microseconds. Both units are part of the metric system where “milli” means one-thousandth and “micro” means one-millionth, so the factor is based on powers of ten.
How to convert milliseconds back to microseconds?
To convert milliseconds to microseconds, multiply the milliseconds value by 1000. For example, 0.02 milliseconds times 1000 equals 20 microseconds. This reverses the division used in converting microseconds to milliseconds.
Are microseconds and milliseconds interchangeable in timing measurements?
They are not interchangeable but related units. Microseconds measure much shorter intervals than milliseconds. Using the wrong unit can cause misunderstandings in time-sensitive applications, so it’s critical to use the correct unit for the timing precision required.
