1 millisecond equals 1.15741e-8 days
How to convert milliseconds to days
A day here is a duration of 86,400 seconds. Unless explicitly labeled Julian, months and years use the mean Gregorian convention (365.2425 days per year; one twelfth per month), rather than the actual length of a particular calendar interval.
d = ms × 1.157407407e-8One millisecond is 1.157407407e-8 days, so a single multiplication converts any value.
0.000000115741 d ≈ 10 × 1.157407407e-8The calendar day is exactly 86,400 s here. Actual solar days vary by milliseconds, and leap seconds have occasionally been added to civil time.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
