A selection of free resources on time (calculators, exercises, games, quizzes, course reminders) that allow you to learn how to calculate with days, hours, minutes and seconds.
Time is a physical measure, its unit of measurement in the international system is the second noted s. It can also be expressed in days noted d, hours noted h, minutes noted min, seconds noted s.
The relations between all its durations, are the following:
These relations allow to make conversions between these different units of time.
Time is used in the calculation of many physical measurements such as average speed or pace.
The average speed it is expressed in meters per second (m/s) in the international system, it is often expressed in km/h. The speed converter will allow you to make speed conversions in different units: kilometers per hour (km/h), meters per second (m/s), miles per hour (mph), feet per second (fps), knots (kn).
