- How many units per
other units (Imperial)
- 12 inches/foot
- 3 feet/yard
- 1760 yards/mile
- conversions from
imperial to metric
- Inches
- 1 inch=2.5 cm
- 1 cm= 4/10 inches
- 1 m= 39 inches
- Feet
- 1 foot= 30cm
- 1 foot= 0.3 m
- 1 m= 3.25 feet
- Yards
- 1 yard= 90 cm
- 1 yard= 0.9m
- Miles
- 1 mile= 1.6 km
- 1km= 6/10 miles

- Definitions
- imperial units
- measurement units commonly
used in the US and some
industries in Canada.
- ie. inch, foot, yard,
mile, nautical mile
- unit analysis
- the method of
converting units and
measuring them in
different units
- ie. 5 feet= 150 cm
- SI measurement system
- a system of units based on the power of 10
- ie. meters, kilograms, seconds
- apex
- the vertex farthest from
the base of an object
- example of an apex is above
- right pyramid
- an object that has one
face that is a polygon
and other faces that are
triangles with a common
vertex
- an example of a
right pyramid is
below
- right cone
- an object with
one circular
base and one
vertex
- i.e. ice cream cone
- slant height
- the distance from a
point on the perimeter of
the base of a cone to
the apex of the cone
- see above for example
- lateral area
- the surface area of
an object not
including its bases
- see below for example
- sphere
- an object where every point
on the surface of the object is
the same distance from the
centre of an object
- see example below
