Metric System- Measurement based on the number 10

S.I. – International system of units: Standard system of measurements which allows scientists to compare data and communicate with each other.

Metric Prefixes Table

|Prefix |Meaning |

|Kilo- (k) |1,000- 1 thousand units |

|Hecto- (h) |100- 1 hundred units |

|Deka- (da) |10- ten units |

|No prefix |1 – one unit |

S.I. Units

| |Information |S.I. Unit |Conversions/ Equations |

|Length |To measure distance. |Meter (m) |1 kilometer= 1000 m |

| |Use a metric ruler | |1 meter = 100 centimeter |

| | | |1 meter = 1000 millimeter |

| | | |1 centimeter = 10 millimeters |

|Mass |The amount of matter in an object. Use a triple beam |Kilogram (kg) |1 Kilogram = 1000 grams |

| |balance to measure | |1 gram = 1000 milligrams |

|Weight |A measurement of gravity acting on an object. |Not S.I. | |

| |Use a scale to measure | | |

|Volume |The amount of space an object takes up. |Cubic meter (m³) |1 m³ = 1,000,000 cm³ |

| | |Also use cm³ of L |1 cm³ = 1 ML |

| |Use a graduated cylinder or regular solid equation to | |1 L = 1000 mL |

| |measure volume. | |1 L = 1000 cm³ |

| | | |-------------------------------------- |

| |Measure volume from the bottom of the meniscus. | |Length x Width x Height= cm³ |

|Density |How much mass is contained in a given volume |Kilograms per cubic |Density = mass over volume |

| | |meters |D=m/v |

| | |Kg/ m³ | |

| | |Also uses g/cm³ or | |

| | |g/mL | |

|Temperature |Use a thermometer. |Kelvin (K) |O K =-273 ºC |

| |Fahrenheit ºF (U. S. ), Celsius ºC (most other | |100 K = - 173 ºC |

| |countries), and Kelvin K (science) | |200 K = -73 ºC |

| | | |273 K = 0 ºC |

| | | |373 K = 100 ºC |

|Time |Use a clock or stopwatch |Second (s) |60 seconds = 1 minute |

| | | |60 minute = 1 hour |
