This module explains scientific notation, the history, and basic operations of the Metric system. The standard method of measurement in science is the Metric system. A giga is 1,000 Mega, and a Tera is 1,000 times of Giga. These have the Mega, Giga and Tera prefixes. The metric system has been called the "International System of Units" or "SI" (from "Système International" in French) since the 1960s. Therefore, 500 ml = 500 ÷ 1,000 = 0.5 literĪ mathematician named Gabriel Mouton began the metric system back in 1,670. A 'deca' therefore means ten times the base unit,' hecto' means ten times the 'deca' or a hundred times the base unit, and 'kilo' means ten times the 'hecto' or a thousand times the base unit. Each unit is 10 times higher than the unit to the right, as we step to the left. The units are larger than the base unit to the left of the base unit. A 'deci' therefore implies 1/10th of the base unit,' centi' is 1/10th of 'deci' or 1/100th of the base unit, and 'milli' is one-tenth of 'centi' or 1/1000th of the base unit. Each unit is 10 times smaller, as we shift to the right. Smaller than the base unit is the units to the right side of the base unit. The figure given illustrates the format of the metric units, which are smaller or larger than the base unit. They are usually derived from the metric units. We use metric numbers to measure smaller or bigger quantities. ![]() One kilometre, for example, is 1000 meters, one kilogram 1,000 grams and one kiloliter is 1,000 litres. ![]() The prefix 'kilo' (meaning 1,000) would be applied to the base unit's 'meter.' This will give us 2,510 kilometres as the length of the River Ganga. Instead of saying, for example, that the river Ganga is 25,10,000 meters, it is 2,510 thousand-meters long. The biggest number and small numbers are expressed as multiples of ten of the base unit to simplify things. For example, in the Metric system, the Length is often calculated in meters, irrespective of whether the length of your car or the length of River Ganga. The unit length of the meter is equivalent to 3.28 feet the gram is a unit mass of roughly 0.0022 pounds and the litre is a unit volume that is equal to 1.05 quarts. The meter, gram and litre are the three most important basic units in the metric system. The simplicity of a metric system is that for each type of quantity measured there is only one unit of measurement. In 1,790, the French National Assembly commissioned the Academy of Sciences to develop a new decimal system of units the system they developed is considered as the metric system. The French Government at the end of the century tried to lessen this problem by creating a measurement system that can be used worldwide. The absence of common standards has led to considerable confusion and inefficiencies in trade between countries. For example, the length was measured in feet, inches, miles, spans, cubits, hands, furlongs, palms, rods, chains, leagues, etc. Dozens of measuring units were widely used worldwide by the 18th century. ![]()
