What is a Millisecond?
The millisecond is one thousandth of a second — imperceptible to humans but critical in electronics, networking, and high-speed photography. Human reaction time is typically 150–300 milliseconds. Internet latency (ping) is measured in milliseconds; 20 ms is considered excellent for online gaming. Modern processors execute hundreds of millions of instructions per millisecond.
What is a Hour?
The hour equals exactly 60 minutes or 3,600 seconds. It has been a core unit of timekeeping since ancient Egypt divided the day into 24 equal parts based on astronomical observation. Work schedules, travel itineraries, and TV programming are universally measured in hours. There are 8,760 hours in a common year (8,784 in a leap year).
