Measurement and Metrics Notes

1. Holt: Ch. 1, Sect. 4

3.  Ancient measurements were based on:
 (1) body parts, such as hands and feet
 (2) food, such as barley
 International System of Units (SI) system was developed by French scientists in the
1700s.
 Simple and reliable
 Also known as the metric system
 Multiples of ten
 Prefixes

5. Base unit is meter (m)
An Olympic-sized swimming
pool is 25 m x 50 m
Distance from King George to
Fredericksburg is 30 kilometers
(km)
A standard piece
of copy paper is
approximately 22
centimeters x 28
centimeters (cm)

6.  The amount of matter in an object
 Base unit is gram (g)
 1000 kg = 1 metric ton
The mass of a
standard tennis
ball is between
57-59 g.
A standard Mini Cooper has
a mass of between 1510-
1690 kilograms (kg).
The mass of a
regulation ping
pong ball is 2700
milligrams (mg).

7.  The amount of space something occupies
 Liquid volume is expressed with base unit liter (L)
 ****Meniscus
 Solid volume is usually expressed in cubic meters (m3)
 How do we calculate volume? 2-D? 3-D?
2L

8.  A measure of how hot (or cold)
something is; specifically, a measure of
the average kinetic energy of the
particles in an object
 SI unit is Kelvin (K), we will use
Celsius (˚C)
