1 millisecond (ms) equals 1000 microseconds (µs).
Table of Contents
A millisecond is a unit of time equal to one thousandth of a second. Since one microsecond is one millionth of a second, converting 1 ms to microseconds means multiplying by 1000, resulting in 1000 µs.

Conversion Formula
The formula to convert milliseconds (ms) to microseconds (µs) involves multiplying the value in milliseconds by 1000. This is because there are 1000 microseconds in every millisecond.
Here’s why it works: 1 second equals 1,000 milliseconds, and 1 second also equals 1,000,000 microseconds. Dividing the microseconds by milliseconds (1,000,000 ÷ 1,000) gives 1000 microseconds per millisecond.
Example calculation:
- Given 1 ms
- Multiply by 1000: 1 × 1000 = 1000
- Result is 1000 microseconds
Conversion Example
- Convert 2.5 ms to microseconds:
- Take 2.5 ms
- Multiply by 1000: 2.5 × 1000 = 2500
- Result: 2500 microseconds
- Convert 0.75 ms to microseconds:
- Start with 0.75 ms
- Multiply by 1000: 0.75 × 1000 = 750
- Result: 750 microseconds
- Convert 10 ms to microseconds:
- Use 10 ms
- Multiply by 1000: 10 × 1000 = 10000
- Result: 10000 microseconds
- Convert 0.001 ms to microseconds:
- Given 0.001 ms
- Multiply by 1000: 0.001 × 1000 = 1
- Result: 1 microsecond

Conversion Definitions
Millisecond (ms): A millisecond is a unit of time equal to one thousandth (1/1000) of a second. It is commonly used to measure short time intervals in technology and science, such as response times in electronics or durations of events in computing.
Microsecond (µs): A microsecond is a unit of time representing one millionth (1/1,000,000) of a second. This unit is used to measure very brief intervals, like signal delays in communication systems or processing times in microcontrollers.
Conversion FAQs
Why does multiplying milliseconds by 1000 give microseconds?
Since 1 millisecond is 1/1000 of a second and 1 microsecond is 1/1,000,000 of a second, there are 1000 microseconds in 1 millisecond. Multiplying the millisecond value by 1000 converts it into microseconds by scaling the smaller unit.
Can the conversion from ms to µs result in decimal microseconds?
Yes, if the millisecond value contains decimals, the converted microseconds can contain decimals too. For example, 0.5 ms equals 500 microseconds precisely, but 0.123 ms equals 123 microseconds. The decimal places depend on the input value.
Is it possible to convert microseconds back to milliseconds?
Yes, converting microseconds back to milliseconds is done by dividing the microsecond value by 1000. This reverses the multiplication, giving the original ms value. For example, 2000 µs equals 2 ms.
Why might negative millisecond values appear in conversion?
Negative millisecond values could represent time differences or offsets before a reference point in certain applications. The conversion process treats negative values the same way as positive ones, multiplying by 1000 to get microseconds.
Are there any practical limits to using ms and µs in timing?
While both units measure very small time intervals, the precision of devices or systems may limit their practical use. Some hardware cannot measure below certain thresholds, making microseconds useful only when supported by accurate timing mechanisms.
