Measurement-A Common Language Length A Standard Measurement System The Metric System
When and why was the metric system invented? The metric system was invented in 1790 The metric system was invented because countries were using many different systems of measurement causing confusion and lack of consistency
Who invented the metric system? The metric system was invented by a group of French scientists Scientists all over the world use the International System of Units to measure:
Length Volume Mass
Temperature Time Metric System A system of measurement that is based on the number 10. A Standard Measurement System
The International System of Units (SI) Figure 1: Calculating How much larger is a kilothan a deka-? 100 times Reading Checkpoint (page 45): SI units are based on multiples of what number?
SI units are based on multiples of 10 Add a zero Subtract a zero Key Concept: Why do scientists use a standard measurement system? Using SI as the standard system of
measurement allows scientists to compare data and communicate with each other about their results Using SI measurement also allows experiments to be repeated and most importantly achieve a desired result Length
What is length? Length is the distance from one point to another The basic unit of length in the SI system is the meter The three units that measure the
length of smaller objects are, Decimeter Centimeter millimeter Complete the Table Below Prefix Meaning
Unit of Length milli one-hundredth meter one-thousand
Complete the Table Below Prefix Meaning milli Onethousandth one-hundredth
Unit of Length millimeter meter one-thousand Complete the Table Below
Prefix Meaning Unit of Length millimeter milli
centi Onethousandth one-hundredth centimeter deci
One-tenth decimeter None one meter
Complete the table below Prefix Meaning Unit of Length
deca ten decameter hecto hundred
hectometer kilo thousand kilometer
Length Measuring Length Every ten centimeters is one decimeter. The longer lines on the metric ruler are called centimeters
The smallest lines on the metric ruler are called millimeters Reading Checkpoint (page 48) One centimeter is divided into how many millimeters? 10
millimeters (mm) Figure 2: Calculating: Measure the turtle in figure 2 from the rear of its shell to the tip of its nose. Record its length in both centimeters and millimeters. 10.5 cm
