Hours
An hour is a unit of time equal to 60 minutes or 3,600 seconds. It’s commonly used to divide the day into manageable portions, helping us structure our daily activities, work schedules, and leisure time. Hours are a fundamental part of timekeeping, found in everything from clocks on the wall to the timing systems of modern technology.
Milliseconds
A millisecond is one-thousandth of a second. This unit of time is often used in contexts where precision is necessary, such as in computer processing, where tasks are completed in milliseconds. It’s also used in measuring the time it takes for high-speed events to occur, like the shutter speed of a camera or the delay in an online game. Milliseconds help us understand and measure processes that are too fast for the human eye to perceive.
