The video tutorial explains the metric system's use in science, focusing on liters as the base unit of volume. It covers the metric staircase, detailing how volume measurements increase or decrease by multiples of 10. The tutorial explores smaller units like deciliters, centiliters, milliliters, microliters, and nanoliters, highlighting their scientific applications. It also discusses larger units such as decaliters, hectoliters, kiloliters, megaliters, and gigaliters, providing real-world examples for context. The video emphasizes the most commonly used units in science: microliters, milliliters, liters, and kiloliters.
