20 milliseconds (msec) equals 0.02 seconds (sec).
To convert 20 msec to sec, you divide the number of milliseconds by 1000 because there are 1000 milliseconds in one second. So, 20 ÷ 1000 = 0.02 seconds.

Conversion Formula
Milliseconds and seconds measure time but at different scales. One second is equal to 1000 milliseconds. So to convert milliseconds to seconds, divide the milliseconds by 1000. This works because milliseconds are thousandths of a second.
Formula:
seconds = milliseconds ÷ 1000
Example with 20 msec:
Step 1: Take the value in milliseconds, 20.
Step 2: Divide by 1000 to find seconds.
20 ÷ 1000 = 0.02 seconds.
Conversion Example
- Convert 50 msec to sec
- Start with 50 milliseconds.
- Divide 50 by 1000.
- Result: 50 ÷ 1000 = 0.05 seconds.
- Convert 125 msec to sec
- Begin with 125 milliseconds.
- Perform 125 ÷ 1000.
- Output: 0.125 seconds.
- Convert 7 msec to sec
- Use 7 milliseconds.
- 7 ÷ 1000 equals 0.007 seconds.
- Convert 300 msec to sec
- Start with 300 milliseconds.
- Divide by 1000, 300 ÷ 1000.
- Result is 0.3 seconds.

Conversion Definitions
msec: Millisecond, abbreviated as msec, is a unit of time equal to one thousandth of a second. It is commonly used when measuring very short time intervals, like delays in electronics or timing events in computing, where precision below a second is needed.
sec: Second, or sec, is the base unit of time in the International System of Units (SI). One second equals 1/60 of a minute and 1/3600 of an hour. Seconds measure everyday durations and serves as standard for timing in science, industry, and daily life.
Conversion FAQs
Can milliseconds be converted to seconds without a calculator?
Yes, converting milliseconds to seconds can be done by dividing the milliseconds number by 1000 in your head or on paper. Since 1000 milliseconds make one second, simple division gives the seconds equivalent even without digital tools.
What happens if I convert negative milliseconds to seconds?
Negative milliseconds represent negative time intervals, which might appear in calculations involving time differences or backward time references. The conversion uses the same division by 1000 rule, so negative values become negative seconds accordingly.
Why are milliseconds important in timing measurements?
Milliseconds provide finer granularity for time measurement than seconds. This is crucial in fields like computing, telecommunications, and physics where events occur faster than a second and precise measurement is critical for performance and accuracy.
Is there any difference between msec and ms?
Both msec and ms stand for milliseconds and represent the same unit of time. The difference is simply abbreviation style; ms is more commonly used in scientific and engineering contexts but both mean one thousandth of a second.
How accurate is converting milliseconds to seconds by dividing by 1000?
The conversion by dividing milliseconds by 1000 is exact mathematically, since 1 sec = 1000 msec exactly. Accuracy depends on the decimal precision you keep during calculation and display, but the formula itself is precise.
