What is the metric unit used for measuring length?

• A. Meter
• B. Liter
• C. Gram
• D. Second

Answer: (A)

Length is measured with the meter in the metric system. The meter is the standard unit for distance, and you can express lengths as meters, with centimeters (1 meter = 100 centimeters) and millimeters (1 meter = 1000 millimeters) as common smaller units. This makes it easy to measure things from small objects to longer distances using a consistent scale. The other units shown measure different quantities: liters measure volume (how much space a substance occupies), grams measure mass (how much matter an object contains), and seconds measure time. So, the metric unit used for measuring length is the meter.
