How to Convert Hours to Milliseconds?

Convert Hours to Milliseconds:

Number of hours = 



1 hour  =  3,600,000 or 3.6 × 106 milliseconds.

To convert hours to milliseconds simply multiply the hours by 3600000 to get milliseconds.

1 hour  =  60 minutes

1 minute  =  60 seconds

1 second  =  1000 milliseconds

So, 1 hour  =  60  ×  60  ×  1000  =  3600000 milliseconds

Example 1: convert 8 hours to milliseconds.
Multiply 8 by 3600000

Total milliseconds in 8 hours  =  8  ×  3600000  =  28,800,000

Hence, there are 28,800,000 milliseconds in 8 hours.
Example 2: convert 0.00008 hours to milliseconds
Multiply 0.00008 by 3600000

Total milliseconds in 0.00008 hours  =  0.00008  ×  3600000  =  288

Hence, there are 288 milliseconds in 0.00008 hours.
Fun Fact:
Sound can travel approximately 100 metres in 288 milliseconds. Usain Bolt took 9580 milliseconds in the world record breaking race in 2009 to complete his 100 metres.
