Is Planck time the smallest unit of time?

Originally Answered: Why is planck the smallest unit of time and space? The Planck time describes the smallest possible time interval for which the known laws of physics are valid. It results from the time it takes for light to travel a Planck length and cause a theoretical change in state.

Is nanosecond the smallest unit of time?

The smallest unit of time that anybody outside of the worlds of physics, mathematics, and science is likely to use or even be aware of is the millisecond (one thousandth of a second) or perhaps the nanosecond (one billionth of a second).

What is the customary unit for time?

“Customary units of time” is a system of measurements commonly used for time in the united states. For measuring time , the U.S. customary system uses the second, minute, hour, day, week, month and year which are the only seven customary time measurements in everyday use.

What are the standard units for time?

What are the units used to measure time?

A unit of time or time unit is any particular time interval, used as a standard way of measuring or expressing duration. The base unit of time in the International System of Units (SI), and by extension most of the Western world, is the second, defined as about 9 billion oscillations of the caesium atom.
