20000 microseconds equals 20 milliseconds.
To convert microseconds to milliseconds, you divide the number of microseconds by 1000 because one millisecond contains 1000 microseconds. So, 20000 microseconds divided by 1000 gives the result in milliseconds.

Conversion Formula
To convert microseconds (µs) to milliseconds (ms), the number of microseconds is divided by 1000. Since 1 millisecond equals 1000 microseconds, the formula is:
Milliseconds = Microseconds ÷ 1000
This works because a millisecond is a larger unit, so you need fewer milliseconds to represent the same amount of time. Dividing microseconds by 1000 reduces the unit scale accordingly.
Example calculation:
- Given 20000 microseconds
- Divide 20000 by 1000: 20000 ÷ 1000 = 20
- Result: 20 milliseconds
Conversion Example
- Convert 4500 microseconds to milliseconds:
- Divide 4500 by 1000
- 4500 ÷ 1000 = 4.5
- Result: 4.5 milliseconds
- Convert 123456 microseconds to milliseconds:
- 123456 ÷ 1000 = 123.456
- Result: 123.456 milliseconds
- Convert 999 microseconds to milliseconds:
- 999 ÷ 1000 = 0.999
- Result: 0.999 milliseconds
- Convert 30000 microseconds to milliseconds:
- 30000 ÷ 1000 = 30
- Result: 30 milliseconds
- Convert 750 microseconds to milliseconds:
- 750 ÷ 1000 = 0.75
- Result: 0.75 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 time intervals, useful in scientific experiments, electronics, and computing where timing is precise and fast.
Milliseconds: A millisecond is a unit of time equal to one thousandth of a second (0.001 seconds). Used in everyday timing such as computer processing speeds, response times, and other applications needing smaller than second precision but longer than microsecond scale.
Conversion FAQs
Why divide microseconds by 1000 to get milliseconds?
Because 1 millisecond contains 1000 microseconds, dividing microseconds by 1000 changes the unit scale from millionths of a second to thousandths. It scales down the number, reflecting the larger unit size of milliseconds compared to microseconds.
Can I convert microseconds to milliseconds without a calculator?
Yes, since the conversion only involves dividing by 1000, you can remove the last three digits from the microseconds number or move the decimal point three places left, which is a simple mental math trick for many values.
Do milliseconds and microseconds measure the same kind of time?
They both measure time but at different scales; microseconds are smaller and more precise units than milliseconds. One millisecond equals 1000 microseconds, so milliseconds measure longer time intervals than microseconds.
What happens if I convert a microseconds value less than 1000?
When converting less than 1000 microseconds, the result in milliseconds will be less than 1, expressed as a decimal. For example, 500 microseconds equals 0.5 milliseconds, showing a fraction of one millisecond.
Is it correct to round the converted milliseconds value?
Rounding depends on context; for precise scientific work, keep decimal places. For everyday uses, rounding to two or three decimal places is often acceptable. Always consider how much precision the task needs before rounding.
