How to Convert From Nanoseconds to Milliseconds

Time follows its own rules. The rule of 60 -- 60 minutes an hour, 60 seconds a minute -- is abandoned when time drops below a second. Units of time then adopt a more structured nature and adhere to rules of the International System of Units or SI.

How to Convert Milliseconds to Hours

A millisecond is a time interval that corresponds to one thousandth of a second. Measuring time to milliseconds usually signifies a high precision required for capturing sport events or for determining exact measurements in scientific experiments. Camera shutter speeds or computer hard drive access time, are typically measured in milliseconds. For various calculations, you may need to convert units of milliseconds as fractions of an hour.
