If the lesson lasts 1 hour its 216,000 milli seconds
There are 3,600,000 milliseconds in an hour. This is calculated by multiplying the number of seconds in an hour (3,600) by the number of milliseconds in a second (1,000). Thus, 1 hour = 3,600 seconds × 1,000 milliseconds/second = 3,600,000 milliseconds.
