decisecond to millisecond
Convert decisecond (ds) to millisecond (ms). Use an editable time converter, conversion formula, and reference table.
1 ds = 100 ms
Conversion formula
One decisecond equals 100 millisecond. Multiply your value in decisecond by this factor to get millisecond. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 decisecond:5 × 100 = 500 ms

About these measurements
Time conversion relates durations expressed in different units.
The base reference used here is the second. One decisecond is 0.1 base units; one millisecond is 0.001 base units.
Important distinctions
A day here is 24 hours and a Julian year is exactly 365.25 days. Calendar months and DST-adjusted days are not fixed durations.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert ds to ms?
Multiply the quantity in ds by 100. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the millisecond to decisecond converter.
