Question
Explain what you mean by standard length and standard time.
Answer
The standard length refers to a fixed distance that serves as a reference for measurements of length. The most widely accepted standard length is the international prototype of the meter, which is a platinum-iridium cylinder kept at the International Bureau of Weights and Measures in France.
Standard time refers to a universally agreed-upon method of measuring time, which is used as a reference for timekeeping around the world. The most widely used standard time is Coordinated Universal Time (UTC), which is based on atomic clocks and is used as the basis for time zones and global communication.
