How do you convert hours to milliseconds?

Answer 1

There are 60 minutes in an hour.

There are 60 seconds in a minute.

There are 1000 milliseconds in a second.

Multiply: 60*60*1000

Answer: 3600000

There are 3600000 milliseconds per hour. Multiply this by the number of hours you want to convert. If you wish to convert milliseconds to hours (the other way around), you need to divide by 3600000.
