Which is the standard unit for length?

• A. Meters
• B. Liters
• C. Kilograms
• D. Degrees Celsius

Answer: (A)

Length is the measurement of how long something is or how far apart two points are. In the International System of Units (SI), the base unit for length is the meter, so meters are the standard unit used to express length. The other options measure different quantities: liters measure volume, kilograms measure mass, and degrees Celsius measure temperature. You’ll also see lengths expressed in derived units like centimeters or kilometers, which come from the meter (1 meter = 100 centimeters, 1 kilometer = 1000 meters).
