This document discusses the history and types of measurement systems. It describes how ancient Egyptians used body parts like hands, feet and elbows to measure things. It then explains the modern metric and US customary systems of units. The metric system uses prefixes like kilo and milli that are powers of 10, while the US customary system includes units like inches, feet and gallons. The document emphasizes that the metric system is now the worldwide standard and easiest to use due to its base-10 numerical structure.

2. What is measurement?
Measurement is finding a
number that shows the size or
amount of something.
We can measure the length,
area, volume, mass, time and
temperature. There are lots of
other things we can measure,
but these are the most common.

3. History of Measurement
In the 3rd century BC
Egypt, people used their
body parts to determine
measurements of
things.
Some of the units are
the span, palm, digit,
foot, cubit and pace.

4. History of Measurements
Span is the distance
from the tip of the little
finger of the little
finger to the tip of the
little finger to the tip of
the thumb of an
outstretched hand

5. History of Measurements
Palm is the distance
across the base of the
four fingers that form
the palm.

6. History of Measurements
Digit is the thickness
or width of the index
finger

7. History of Measurements
Foot is the length of
the foot.

8. History of Measurements
Cubit is the distance
from the tip of the
middle finger of an
outstretched hand to
the front of the
elbow

9. History of Measurements
Pace is the
distance of one
full step

10. System of Measurement
Metric System
US Standard Units or Customary
Units

11. System of Measurement
Metric System
The world standard for measurement.
Nowadays the use of the metric system of
measurement is recommended because
computations are easier in this system since it
uses the power of 10.
There are prefixes that describe each power of
10.

12. System of Measurement
US Standard Units or US
Customary Units
A system of measurement used in the
United States.
A modern metric system which is the vast
majority of U.S. customary units have
been defined in terms of the meter and the
kilogram.
