  3. Mass • Gram • The standard unit of mass in the metric system is the gram. Other units of mass and their equivalents in grams are as follows:1 milligram = 0.001 gram1 centigram = 0.01 gram1 decigram = 0.1 gram1 kilogram = 1000 grams

  4. Mass • Gram • We symbolize these masses as follows:1 milligram = 1 mg1 centigram = 1 cg1 decigram = 1 dg1 gram = 1 g1 kilogram = 1 kg

  5. Length • Meter • The standard unit of length in the metric system is the meter. Other units of length and their equivalents in meters are as follows: 1 millimeter = 0.001 meter1 centimeter = 0.01 meter1 decimeter = 0.1 meter1 kilometer = 1000 meters

  6. Length • Meter • We symbolize these lengths as follows:1 millimeter = 1 mm1 centimeter = 1 cm1 meter = 1 m1 decimeter = 1 dm1 kilometer = 1 km

  7. Volume • Litre / Liter • The standard unit of volume in the metric system is the liter. One liter is equal to 1000 cubic centimeters in volume. Other units of volume and their equivalents in liters are as follows: 1 milliliter = 0.001 liter1 centiliter = 0.01 liter1 deciliter = 0.1 liter1 kiloliter = 1000 liters

  8. Volume • Litre / Liter • 1 milliliter = 1 ml1 centiliter = 1 cl1 deciliter = 1 dl1 liter = 1 l1 kiloliter = 1 kl

  9. Time • The following conversions are useful when working with time:1 minute = 60 seconds1 hour = 60 minutes = 3600 seconds1 day = 24 hours1 week = 7 days1 year = 365 1/4 days (for the Earth to travel once around the sun

  10. Temperature • Degrees Celsius • Temperature is expressed in degrees Celsius in the metric system. The boiling point of water (at sea level) is 100°Celsius, or 100°C. The freezing point of water (at sea level) is 0° Celsius. A hot day is about 30° Celsius.

  11. Decimals in Metric Measurement • Prefix- Multiply by • milli- 0.001 • centi- 0.01 • deci- 0.1 • deka- 10 • hecto - 100 • kilo- 1000

  12. Decimals in Metric Measurement • So for example:1 hectometer = 100 meters1 centigram = 0.01 gram3 milliliters = 3 × (0.001 liters) = 0.003 liters0.9 kilometers = 0.9 × (1000 meters) = 900 meters
