45 milliseconds (ms) is equal to 0.045 seconds (s).
To convert milliseconds to seconds, you divide the number of milliseconds by 1000 because 1 second contains 1000 milliseconds. So, 45 ms divided by 1000 equals 0.045 s.

Conversion Formula
The conversion formula to change milliseconds (ms) to seconds (s) is:
seconds = milliseconds ÷ 1000
This formula works because a second contains exactly 1000 milliseconds; therefore, dividing the milliseconds value by 1000 gives its equivalent in seconds.
For example, converting 45 ms to seconds step-by-step:
- Start with 45 milliseconds.
- Divide 45 by 1000: 45 ÷ 1000 = 0.045.
- The result is 0.045 seconds.
Conversion Example
- Convert 120 ms to seconds:
- Take 120 milliseconds.
- Divide 120 by 1000: 120 ÷ 1000 = 0.12.
- So, 120 ms equals 0.12 seconds.
- Convert 350 ms to seconds:
- Start with 350 milliseconds.
- Divide 350 by 1000: 350 ÷ 1000 = 0.35.
- The equivalent in seconds is 0.35 s.
- Convert 5 ms to seconds:
- Begin with 5 milliseconds.
- Divide 5 by 1000: 5 ÷ 1000 = 0.005.
- Therefore, 5 ms equals 0.005 seconds.
- Convert 999 ms to seconds:
- Use 999 milliseconds.
- Divide 999 by 1000: 999 ÷ 1000 = 0.999.
- Thus, 999 ms is 0.999 seconds.

Conversion Definitions
ms (millisecond): A millisecond is a unit of time equal to one thousandth (1/1000) of a second. It’s used to measure very short durations, like response time in electronics or timing in computer processes, representing a fraction of a second.
s (second): A second is the base unit of time in the International System of Units (SI), defined by the duration of 9,192,631,770 periods of radiation of cesium-133. Seconds are common for measuring everyday time intervals and scientific measurements.
Conversion FAQs
Why do we divide milliseconds by 1000 to get seconds?
Milliseconds are one-thousandth of a second, so to convert any number of milliseconds to seconds, dividing by 1000 scales the value down accordingly. This division changes the unit from a smaller fraction to the full second unit.
Can I convert milliseconds to seconds without a calculator?
Yes, since milliseconds are thousandths of a second, you can move the decimal point three places to the left. For example, 1500 ms becomes 1.500 seconds by shifting the decimal, which is equivalent to dividing by 1000.
Is 45 ms a long time in everyday use?
Forty-five milliseconds is a very brief time span, less than a blink of an eye. For reference, human reaction time is about 200-300 milliseconds, so 45 ms is quite fast in practical terms.
What happens if I convert 0 ms to seconds?
If you convert 0 milliseconds to seconds, the result is 0 seconds, because zero divided by any number remains zero. It means no time has elapsed.
Are milliseconds used in all countries for time measurement?
Milliseconds are part of the SI system, so they are recognized worldwide for scientific and technical measurements. However, everyday time conversations rarely use milliseconds unless precision timing is necessary.
