1 Why do you think scientists use the metric system?

2 The Metric System An internationally agreed upon system, based on the number 10 Officially called the SI system, built on a foundation of 7 "base units". What it is

3 The Metric System An internationally agreed upon system, based on the number 10 Officially called the SI system, built on a foundation of 7 "base units". Mass - gram (g) What it is The 4 base units well use

5 The Metric System An internationally agreed upon system, based on the number 10 Officially called the SI system, built on a foundation of 7 "base units". Mass - gram (g) Volume - Liter (L) Distance - meter (m) What it is The 4 base units well use

6 The Metric System An internationally agreed upon system, based on the number 10 Officially called the SI system, built on a foundation of 7 "base units". Mass - gram (g) Volume - Liter (L) Distance - meter (m) Time - second (s) What it is The 4 base units well use

7 The Metric System We attach prefixes – a group of letters – in front of each metric unit to tell us how much bigger or smaller we want it. prefixlettersize megaM 1,000,000 kiloK 1,000 hectoH 100 dekadk 10 unit- 1 decid 0.1 centic 0.01 millim microμ prefixes
