Convert days to seconds
Day
A day is approximately the period of time during which the Earth completes one rotation around its axis. A solar day is the length of time which elapses between the Sun reaching its highest point in the sky two consecutive times. Days on other planets are defined similarly and vary in length due to differing rotation periods, that of Mars being slightly longer and sometimes called a sol.
Second
The second (symbol: s , abbreviation: sec ) is the base unit of time in the International System of Units (SI) (French: Système International d’unités), commonly understood and historically defined as 1/86400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each. Analogue clocks and watches often have sixty tick marks on their faces, representing seconds (and minutes), and a "second hand" to mark the passage of time in seconds. Digital clocks and watches often have a two-digit seconds counter. The second is also part of several other units of measurement like metres per second for velocity, metres per second per second for acceleration, and cycles per second for frequency.
