How to Convert Milliseconds to Hours
To convert a measurement in milliseconds to a measurement in hours, divide the time by the following conversion ratio: 3,600,000 milliseconds/hour.
Since one hour is equal to 3,600,000 milliseconds, you can use this simple formula to convert:
hours = milliseconds ÷ 3,600,000
The time in hours is equal to the time in milliseconds divided by 3,600,000.
For example, here's how to convert 5,000,000 milliseconds to hours using the formula above.
hours = (5,000,000 ms ÷ 3,600,000) = 1.388889 hr
Milliseconds and hours are both units used to measure time. Keep reading to learn more about each unit of measure.
