The Metric System (SI Units) is user-friendly due to its base-10 format, making conversions straightforward. This guide explores essential units like meters for length, liters for volume, and grams for mass, illustrating how smaller units easily convert to larger ones and vice versa. You'll learn about metric prefixes, such as kilo- and milli-, which denote multiples of 10, enhancing clarity. Understanding these principles simplifies measuring and helps you choose the most appropriate unit for various objects, facilitating everyday calculations.

Using the Metric System S.I. units are so easy to work with because they are based on multiples of 10!
How easy is this??? • There has to be a better way… Converting Standard Measurements
In The Metric System… • There is one basic unit for… • Length (meter) • Volume (liter) • Mass (gram) • Each smaller unit is easy to convert to the larger unit and vice versa! • This chart can be used for each of the basic units • The values do not change for liters… • Or Grams!
Using the Metric System is easy!!! • To simplify things, very large and very small objects are expressed as multiples of ten of the base unit • For example… A “5,000” meter long race can also be written as a “five thousand” meter, or as “5K” (5 kilometer) long race! • A grain of salt is “0.001” meters long, or “one one-thousandth of a meter, or “millimeter” in length • Metric prefixes can be used with any base unit • For example… • A kilometer is 1,000 meters • A kilogram is 1,000 grams • A kiloliter is 1,000 liters
Using the Metric System is easy!!! • Base the subunit you use on whichever is closest to the size of the object you are measuring • It wouldn't make sense to measure your weight in grams for the same reason that you wouldn't measure it in ounces - the unit is too small • You would express your weight in a unit that makes sense, in this case: kilograms, because 1 kilogram is equal to 1000 grams • (1 kilogram = 2.2 lbs) 1 kilogram 1000 grams They are the same!
How do I do it? • The metric system is based on multiplying or dividing your units by 10 • This moves your decimal point to the left or right • It does NOT change the numbers you use! • The six important prefixes used in the Metric System are…
