The Metric System

What is the Metric System The standard measurement system for science All sciences use the metric system (including this class) Conversions will be a necessary skill not only for this class, but for chemistry and physics This system is much easier to use than the English Imperial System

Conversion Steps 1. Rewrite given number, write in decimal (if not present) 2. Find the beginning and ending units on your conversion chart 3. Count how many times you ‘jump’/ Which way do you move? 4. Draw in jumps from beginning decimal/ Draw a new decimal and cross out the beginning decimal 5. Add zeros in the jumps 6. Write your final answer with the new unit

Examples 1. 1.85m = ___________cm 2. 3.5 km = ___________cm 3. 4.6 km = ___________ mm 4. 298 m = ___________ km 5. 455cm = ___________km

More Practice 1. 0.55km = ___________mm 2. 1,549 cm = __________m 4. 22,543 um = ___________cm 5. 72 cm =_______________um
