What is the standard unit used to measure time in the metric system?

• A. Hours
• B. Seconds
• C. Minutes
• D. Days

Answer: (B)

The standard unit for time in the metric system is the second. In the International System of Units (SI), the second is the base unit of time, chosen for universality and precision. More convenient units like minutes, hours, and days exist, but they are defined by multiplying the second (60 seconds in a minute, 60 minutes in an hour, 24 hours in a day). For very precise timing, scientists also use smaller units such as milliseconds or microseconds, all based on the same second. That’s why seconds are the standard unit in the metric system.
