1 millisecond equals 1000 microseconds.
Table of Contents
Since one millisecond is one-thousandth of a second, and one microsecond is one-millionth of a second, converting milliseconds to microseconds requires multiplying by 1000. This increase happens because microseconds are smaller units than milliseconds.

Conversion Formula
The conversion formula from milliseconds to microseconds is:
Microseconds = Milliseconds × 1000
Because 1 millisecond equals 0.001 seconds, and 1 microsecond equals 0.000001 seconds, there are 1000 microseconds in a millisecond.
Example:
- Start with 1 millisecond
- Multiply by 1000 to get microseconds: 1 × 1000 = 1000 microseconds
So, 1 millisecond is 1000 microseconds.
Conversion Example
- Convert 3 milliseconds to microseconds:
- Multiply 3 by 1000
- 3 × 1000 = 3000 microseconds
- Therefore, 3 milliseconds equals 3000 microseconds
- Convert 0.5 milliseconds to microseconds:
- Multiply 0.5 by 1000
- 0.5 × 1000 = 500 microseconds
- So, 0.5 milliseconds is 500 microseconds
- Convert 12.75 milliseconds to microseconds:
- Multiply 12.75 by 1000
- 12.75 × 1000 = 12750 microseconds
- Thus, 12.75 milliseconds equals 12750 microseconds
- Convert -7 milliseconds to microseconds:
- Multiply -7 by 1000
- -7 × 1000 = -7000 microseconds
- Hence, -7 milliseconds is -7000 microseconds

Conversion Definitions
Milliseconds: A millisecond is a unit of time equal to one-thousandth (1/1000) of a second. This unit measure is used to express durations that are shorter than a second but longer than a microsecond, often in computing, telecommunications, and scientific measurements.
Microseconds: A microsecond is a unit of time equal to one-millionth (1/1,000,000) of a second. It is used in contexts requiring extremely precise timing, such as electronics, high-speed data processing, and physics experiments involving very short time intervals.
Conversion FAQs
Can milliseconds be negative and still convert to microseconds?
Yes, milliseconds can have negative values to represent time intervals before a reference point, such as timestamps in some systems. When converting negative milliseconds to microseconds, multiply by 1000 as usual, preserving the negative sign.
Why does multiplying by 1000 convert milliseconds to microseconds?
This happens because a microsecond is 1000 times smaller than a millisecond. So, each millisecond contains 1000 microseconds. Multiplying by 1000 scales the value from the larger unit to the smaller unit.
Is there any loss of precision when converting 1 millisecond to microseconds?
No, converting 1 millisecond to microseconds is an exact conversion. Since both units are decimal subdivisions of a second, the multiplication by 1000 results in a precise value without rounding errors.
How can I convert milliseconds to microseconds programmatically?
You can multiply the millisecond value by 1000 in most programming languages. For example, in JavaScript: microseconds = milliseconds * 1000; This simple arithmetic operation converts the unit correctly.
What happens if I convert fractional milliseconds to microseconds?
Fractional milliseconds convert by multiplying the fraction by 1000, resulting in fractional microseconds. For example, 0.25 milliseconds is 250 microseconds. This allows precise time measurement at sub-millisecond levels.
