Measurement-A Common Language Metric system.
Metric System A system of measurement used by the majority of countries on Earth based on the number 10 Some times called the S.I. system
Basic Measurements Meter – measures length Liter – measures volume Gram – measures mass
Converting Some times we need to go from one size to another size. So we give each different size a pre-fix.
Metric Units
How to Convert Step 1: Determine if you are going to go up or down the ladder. Step 2: Determine how many steps there are from the units you started with to the units you need to get to. Step 3: Move the decimal point the same amount of places and in the same direction as in steps 1 & 2.

How does a triple-beam balance work? A triple-beam balance works by comparing the mass of the object you are measuring to a known mass When you use a triple-beam balance, you: Place the object on the pan Shift the riders on the beams until them balance the mass of the object Start with the large rider (increments of 100) Next, the medium sized rider (increments of 10) Lastly, the small rider (increments of 1)
Why do scientists prefer to use the mass of an object instead of its weight? Scientists prefer to use an objects mass instead of its weight because mass does not change when the force of gravity does
