20 microseconds equals 0.02 milliseconds.
To convert microseconds to milliseconds, you divide the number of microseconds by 1000 because 1 millisecond contains 1000 microseconds. Therefore, 20 microseconds is 20 divided by 1000, which gives 0.02 milliseconds.

Conversion Formula
Microseconds and milliseconds are both units of time, but milliseconds are 1000 times longer than microseconds. The formula to convert microseconds (µs) to milliseconds (ms) is:
milliseconds = microseconds ÷ 1000
This works because 1 millisecond equals 1000 microseconds. Dividing the microseconds value by 1000 scales it down to milliseconds.
Example:
- Given 20 microseconds, divide 20 by 1000.
- 20 ÷ 1000 = 0.02 milliseconds.
Conversion Example
- Convert 500 microseconds to milliseconds:
- Divide 500 by 1000.
- 500 ÷ 1000 = 0.5 milliseconds.
- Convert 1500 microseconds to milliseconds:
- Divide 1500 by 1000.
- 1500 ÷ 1000 = 1.5 milliseconds.
- Convert 75 microseconds to milliseconds:
- Divide 75 by 1000.
- 75 ÷ 1000 = 0.075 milliseconds.
- Convert 0 microseconds to milliseconds:
- Divide 0 by 1000.
- 0 ÷ 1000 = 0 milliseconds.

Conversion Definitions
Microseconds: A microsecond (µs) is a unit of time equal to one millionth of a second (0.000001 seconds). It measures extremely short durations, often in scientific and technological fields where precise timing is required, such as electronics and physics experiments.
Milliseconds: A millisecond (ms) is a unit of time equal to one thousandth of a second (0.001 seconds). It is used to measure short time intervals, commonly found in computer processing speeds, audio timings, and everyday timing tasks where seconds are too long to be precise enough.
Conversion FAQs
Why divide microseconds by 1000 to get milliseconds?
Because 1 millisecond contains 1000 microseconds, dividing microseconds by 1000 scales down the value to milliseconds. This is a direct relationship from the metric prefixes where “milli” means 1/1000 and “micro” means 1/1,000,000.
Can microseconds be converted directly to seconds?
Yes, microseconds can be converted to seconds by dividing the microseconds by 1,000,000, since there are one million microseconds in one second. For example, 20 microseconds is 20 ÷ 1,000,000 = 0.00002 seconds.
Does converting microseconds to milliseconds cause loss of precision?
Sometimes it can. When converting small microsecond values to milliseconds, the result might be a very small decimal number that could be rounded depending on display or calculation precision. This might hide very small time differences if not handled carefully.
Are negative microseconds valid in conversions?
Negative microseconds are unusual but can appear in certain mathematical or signal processing contexts where time differences or offsets are measured. The conversion process still works by dividing by 1000, keeping the sign intact.
How to handle fractional microseconds in conversion?
If the microseconds value includes decimals, simply divide that decimal number by 1000 as well. For example, 20.5 microseconds converts to 0.0205 milliseconds by the same formula without any extra steps.
