20 microseconds is equal to 0.02 milliseconds.
To convert microseconds to milliseconds, you divide the number of microseconds by 1,000 since 1 millisecond equals 1,000 microseconds. So, 20 microseconds divided by 1,000 gives 0.02 milliseconds.

Conversion Formula
The formula to convert microseconds to milliseconds is simple: divide the microseconds value by 1,000. This works because 1 millisecond equals 1,000 microseconds.
Formula:
Milliseconds = Microseconds ÷ 1,000
Why this works: Microseconds are smaller units than milliseconds, exactly one thousand times smaller. So you get milliseconds by reducing the microseconds by a factor of 1,000.
Example calculation:
- Given: 20 microseconds
- Divide 20 by 1,000: 20 ÷ 1,000 = 0.02
- Result: 0.02 milliseconds
Conversion Example
- Convert 50 microseconds to milliseconds:
- Start with 50 microseconds
- Divide 50 by 1,000 (because 1 ms = 1,000 µs)
- 50 ÷ 1,000 = 0.05 milliseconds
- Final result: 0.05 milliseconds
- Convert 125 microseconds to milliseconds:
- Take 125 microseconds
- Divide 125 by 1,000
- 125 ÷ 1,000 = 0.125 milliseconds
- Result is 0.125 milliseconds
- Convert 7 microseconds to milliseconds:
- Start from 7 microseconds
- Divide by 1,000
- 7 ÷ 1,000 = 0.007 milliseconds
- Answer: 0.007 milliseconds
- Convert 200 microseconds to milliseconds:
- Use 200 microseconds
- Divide 200 by 1,000
- 200 ÷ 1,000 = 0.2 milliseconds
- So, 0.2 milliseconds

Conversion Definitions
Microseconds: A microsecond is one millionth of a second, represented by the symbol µs. It’s a unit of time used to measure extremely short durations, such as in electronics, computing, and physics, where precision timing at microsecond levels is necessary for tasks like signal processing or high-speed measurements.
Milliseconds: A millisecond is one thousandth of a second, symbolized as ms. It is commonly used to measure intervals longer than microseconds but shorter than seconds, useful in fields like computer response times, audio processing, and timing events that occur faster than a second but slower than microseconds.
Conversion FAQs
Can microseconds be converted directly to seconds without using milliseconds?
Yes, microseconds can be converted straight to seconds by dividing the microseconds value by 1,000,000 since 1 second equals 1,000,000 microseconds. For example, 20 microseconds is 20 ÷ 1,000,000 = 0.00002 seconds.
Why do we divide microseconds by 1,000 to get milliseconds?
Because 1 millisecond contains 1,000 microseconds, dividing microseconds by 1,000 reduces the smaller unit into the larger one. This division scales down the microsecond count to milliseconds, which are bigger units of time.
Is the conversion from microseconds to milliseconds always exact?
Yes, the conversion is exact mathematically because it involves dividing by a fixed number, 1,000. However, the displayed result might be rounded if you limit decimal places, but the underlying conversion remains precise.
What happens if you convert a negative microseconds value?
Negative microseconds represent a time before a reference point or zero, such as in timing offsets. When converted to milliseconds, the negative value is divided by 1,000 as usual, preserving the negative sign but changing the unit scale.
Can this conversion be used for large microseconds values, like millions?
Yes, the formula works for any value. For example, 1,000,000 microseconds divided by 1,000 equals 1,000 milliseconds, or 1 second. The conversion scales properly regardless of the size of the microseconds value.
