Systems of Measurement: Base 10, Standard, and Metric
undefined
“Systeme International”
Base 10 System
Works for all units of measurement
length, volume, time, and mass
The Standard or English System is what you
are used to using in the US … MOST other
countries use METRIC!
Length = Inch or Foot
Volume = Cup, ounce, gallon
Time = Second
Mass = Pound
The Metric system is used for ALL sciences.
Length = Meter (m)
Volume = Liter (L)
Time = Second (s)
Mass = Gram (g)
Metric
10 millimeters = 1 centimeter
10 centimeters = 1 decimeter
10 decimeters = 1 meter
10 meters = 1 dekameter
10 dekameters = 1 hectameter
10 hectameters = 1 kilometer
English
12 inches = 1 foot
3 feet = 1 yard
5.5 yards = 1 rod
320 rods = 1 mile
5280 feet = 1 mile
Base 10 allows scientists to easily change
units to make numbers more manageable
How many days old are you?
Easier to use years huh…
Science is all about combining observations
into big ideas
Sometimes we describe
▪
Dogs are larger than mice
Sometimes we take measurments
▪
The average height of a dog is 0.56 m
Those Observations must be PRECISE AND
ACCURATE
ACCURATE
As close to the known value as possible
PRECISE
Every measurement is of the same thing is close
to one another

Systems of measurement play a crucial role in science and everyday life. This content explores the Base 10, Standard, and Metric systems, illustrating how they are used for length, volume, time, and mass measurements. Understanding the differences between these systems can help in converting units effectively and enhancing precision and accuracy in scientific observations and measurements.
