Conversions in The Metric System

Conversions What could you measure using…. Meters. Grams. Liter. How do these measures compare to the English units of measuring? Do they measure the same types of things? How do you Know? n

Conversions using the SI *Metric units are families. The meter family, the gram family, and the liter family. *When we measure something using a metric unit, we can change the unit to another metric unit within the same base unit or family. For example, we can change centimeters to millimeter, kilometers, etc…

Conversions SI Cont’d However, we can not change meters to grams or liters because the units measure different things. Remember…. Each unit has a family and must stay in its family…. -What did we say grams measured? mass -How about liters? capacity -And meters? length Can we change meters to grams? or grams to liters? or meters to liters? Why or why not? sometimes, we may want to change one unit to another in its family. (centimeters to decameters)

Conversions SI Cont’d I am going to show you an easy way to convert units within a certain base unit. Liters, meters, grams k stands for kilo h stands for hecto dc stands for deca d stands for deci c stands for centi m stands for milli *notice that there are two d’s and they each stand for something different. To convert, start at the from unit and count over either up or down to the unit. However many places you count and which way you move, is the amount of places and direction the decimal is moved.

Conversions SI Cont’d n Examples: 32 kilograms=____grams how many places do we count to get to grams? 3 what direction did we move? dowm so the answer would be 32000 we move our decimal point three places to the right 40 milligrams=____dekagrams how many places do we count to get to grams? 4 what direction did we move? Up so the answer would be. 0040 we move our decimal point four places to the left

Converting to English Scale How do these measures compare to the English units of measuring? Do they measure the same types of things? How do you Know? Using the table below, you can convert from the SI units to the English units.
