20 microseconds equals 0.02 milliseconds.
Table of Contents
To convert 20 microseconds to milliseconds, you divide by 1000 because there are 1000 microseconds in one millisecond. So, 20 divided by 1000 equals 0.02 milliseconds.

Result in milliseconds:
Conversion Formula
The formula used to convert microseconds (µs) to milliseconds (ms) is:
milliseconds = microseconds ÷ 1000
This formula works because 1 millisecond equals 1000 microseconds. By dividing the number of microseconds by 1000, you find out how many milliseconds are in that amount.
For example, converting 20 microseconds:
- Start with 20 microseconds.
- Divide by 1000: 20 ÷ 1000 = 0.02.
- The result is 0.02 milliseconds.
Conversion Example
- Convert 50 microseconds to milliseconds:
- Take 50 microseconds.
- Divide 50 by 1000: 50 ÷ 1000 = 0.05.
- Result: 0.05 milliseconds.
- Convert 125 microseconds to milliseconds:
- Start with 125 microseconds.
- Divide by 1000: 125 ÷ 1000 = 0.125.
- Answer: 0.125 milliseconds.
- Convert 7 microseconds to milliseconds:
- Begin with 7 microseconds.
- Divide 7 by 1000: 7 ÷ 1000 = 0.007.
- Result: 0.007 milliseconds.
- Convert 300 microseconds to milliseconds:
- Take 300 microseconds.
- Divide 300 by 1000: 300 ÷ 1000 = 0.3.
- The output: 0.3 milliseconds.
- Convert 999 microseconds to milliseconds:
- Starting with 999 microseconds.
- Divide by 1000: 999 ÷ 1000 = 0.999.
- Result: 0.999 milliseconds.

Conversion Definitions
Microseconds: A microsecond is a unit of time equal to one millionth of a second (0.000001 seconds). It is used to measure very short intervals, often in electronics, computing, and physics where events happen extremely fast and require precise timing.
Milliseconds: A millisecond is a unit of time equal to one thousandth of a second (0.001 seconds). It is commonly used to express durations in human-scale timing, such as in computer response times, audio processing, and various timing measurements.
Conversion FAQs
Why do we divide microseconds by 1000 to get milliseconds?
Because 1 millisecond equals 1000 microseconds, dividing by 1000 converts microseconds into the corresponding millisecond value. This scaling accounts for the difference in size between the two units.
Can the conversion result be greater than the original microsecond value?
No, since a millisecond is larger than a microsecond, the converted value in milliseconds will always be smaller than the original microseconds if the input is positive. For example, 20 microseconds converts to 0.02 milliseconds.
Is this conversion affected by time zones or daylight saving?
No, this conversion is purely mathematical and based on units of time, independent from calendar adjustments like time zones or daylight saving changes.
Are negative microseconds valid for conversion?
Negative microseconds may represent time offsets or errors in some contexts. The mathematical conversion still works by dividing by 1000, but the physical meaning depends on the application.
How precise is this conversion when using decimal places?
The conversion is exact mathematically, but when rounding to decimal places, some precision is lost. For example, 20 microseconds equals 0.02 milliseconds exactly, but others might result in repeating decimals that need rounding.
