Mathematics and Measurement
This is the language of science
mathematics
(this is how they relate to each other)
This system of measurement was designed by French scientists to be simpler to learn and use than the F.P.S. system
metric system
Mass in a certain volume
density
The system of measurement accepted as the standard for scientific and technical purposes
International System of Measurement (SI)
F = 9/5 (C + 40) - 40
Convert from Celsius to Fahrenheit
The closeness of a measurement of the quantity's actual value
accuracy
This metric prefix represents a unit to the power of 102
hecto-
This is a sample of what to expect - please be prepared!
volume
The SI unit for mass
kilogram
K = C + 273.15
Convert from Celsius to Kelvin
A mathematical statement that two expressions are equal
equation
The prefix hecto- represents this power of ten
102
This is an example of what to expect on the test - be prepared!
The best way to determine the volume of a large, irregularly shaped solid
C = 5/9 (F + 40) - 40
convert Fahrenheit to Celsius
p = m/V
Finding the density of an object
How closely several measurements match each other
Precision
This system of measurement adds a prefix to each basic unit to make it larger or smaller
metric system
The ratio of the density of a substance to the density of a standard substance
specific gravity
V = lwh
volume of rectangular prism
d = p (substance) / p (water)
calculate specific gravity
When a number is written in scientific notation, only the first factor contains this
significant digits
A specific measure to which other measures are compared to ensure uniformity
standard of measure
Equation of equivalent ratios
proportion
m = pV
find the mass of an object
V (object) = v (final) - v (initial)
calculate volume by fluid displacement
