Seconds, minutes, and hours
- We use seconds, minutes, and hours to tell the time of the day and we use days, months, and years to tell the date. Seconds, minutes, and hours are smaller units of time, and days, months, and years are bigger units of time.

What is the basic unit of time in the International System?
A unit of time 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.
Use units of time to measure or indicate the length of time, the interval of an event, or the duration between two events. The second (s or sec) is often referred to as a base time unit in the International System of Units, or the SI unit of time.
In this article, we shall explore the concept of metric and imperial units of measurement. We will also discuss the various measurement units used for measuring length, mass, time, temperature, and volume.
Time is used to measure the duration of a phenomenon, the period between 2 events. On Earth, time and its units are based on the rotation of the Earth and the Earth’s revolution around the Sun. Time can be measured using a watch or a stopwatch.
Jul 15, 2024 · What are Units of Time? Time is quantified through various units that structure our understanding and organization of the world. The second (s), the SI base unit, provides a fundamental measure for scientific accuracy and everyday timing, ensuring precision across many disciplines.

Since 1967, the International System of Measurements bases its unit of time, the second, on the properties of caesium atoms. SI defines the second as 9,192,631,770 cycles of the radiation that corresponds to the transition between two electron spin energy levels of the ground state of the 133 Cs atom.
The base unit for time is the second (the other SI units are: metre for length, kilogram for mass, ampere for electric current, kelvin for temperature, candela for luminous intensity, and mole for the amount of substance). The second can be abbreviated as s or sec.
