Convert day to millisecond
Please provide values below to convert day [d] to millisecond [ms], or Convert millisecond to day.
1 d = 86400000 ms. To convert day to millisecond, multiply the value by 86400000; to go the other way, divide by it (1 ms = 1.15740740741e-08 d). Both units measure time and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 d = 86400000 ms
- 1 ms = 1.15740740741e-08 d
- 10 d = 864000000 ms

Day
A day is a unit of time representing the period of one complete rotation of the Earth on its axis, typically lasting 24 hours.
History/Origin
The concept of a day has origins in ancient civilizations observing the cycle of day and night. The 24-hour day was standardized in the modern era, with the division into hours dating back to ancient Egypt and further refined through the adoption of mechanical clocks.
Current Use
The day is used universally to measure time intervals, schedule activities, and organize daily life, with the 24-hour system being the standard in most countries worldwide.
Millisecond
A millisecond (ms) is a unit of time equal to one thousandth of a second.
History/Origin
The millisecond was introduced as a standard unit of time measurement with the development of precise timekeeping and scientific instrumentation in the 20th century, particularly with the advent of electronic clocks and digital technology.
Current Use
Milliseconds are widely used in computing, telecommunications, and scientific measurements to denote very short durations, such as in data processing, network latency, and high-frequency trading.
