Convert from day to microsecond formula

Total microsecond = Total day x 86400000000

For example, if you want to convert 10 Day to Microsecond then,

10 d = 10 x 86400000000 = 864000000000 μs

The unit of measurement "day" is defined as 86,400 SI seconds and symbolized d. A day is usually 24 hours, plus or minus a possible leap second in Coordinated Universal Time (UTC), and occasionally plus or minus an hour in those locations that change from or to daylight saving time.


A microsecond (symbol: μs) is an SI unit of time equal to one millionth of second. A microsecond is equal to 1000 nanoseconds. Time units ranging between 10−5 and 10−4 seconds are typically expressed as tens or hundreds of microseconds.
