|
area
| |
A measurement of the amount of space contained within a flat, enclosed shape.
|
|
base unit
| |
A unit of measurement that can be determined by taking one measurement
without having to combine any other measurement. Length, mass, and
temperature are examples of base units. |
|
CNC lathe
| |
A lathe that is controlled by a computer running programs driven by numerical data.
|
|
derived unit
| |
A unit of measurement that is determined by combining one or more
measurements. Miles per hour or kilometers per hour are examples of
derived units. |
|
diameter
| |
The distance from one end of the circle to the opposite end through the center.
|
|
digital caliper
| |
A measuring instrument typically used in inspection that contains two
pairs of jaws on one end and a long beam containing a marked scale of
unit divisions. Digital calipers display measurements in both English
and Metric units. |
|
English system
| |
A standard system of measurements based on the inch, pound, and
Fahrenheit degrees. English measurements are primarily used in the
United States and England. |
|
International System of Units
| |
Another name used for the Metric System. International System of Units is often abbreviated as SI.
|
|
kilometers per hour
| |
A derived unit that indicates speed, or how many kilometers an object
travels in one hour. Kilometers per hour is calculated by dividing the
distance traveled by the time elapsed. |
|
length
| |
A measurement of distance from one point to another.
|
|
mass
| |
A measurement of the heaviness of an object. Mass is usually expressed
in Metric units. In the shop, weight and mass are used interchangeably.
|
|
measurement
| |
The act or process of measuring an object. We use units of measurement daily.
|
|
Metric system
| |
A standard system of measurements based on the meter, kilogram, and
Celsius degrees. The metric system is internationally recognized. |
|
miles per hour
| |
A derived unit that indicates speed, or how many miles an object travels
in one hour. Mph is calculated by dividing the distance traveled by the
time elapsed. |
|
prefix
| |
A word attached to the beginning of another word. Prefixes are attached
to the beginning of a base unit of a Metric measurement to indicate the
specific power of ten. |
|
pressure
| |
The amount of force applied upon an object. Pressure is a derived unit
that combines time, area, and mass. |
|
rectangle
| |
A shape with four angles and four sides forming 90° angles.
|
|
speed
| |
The rate at which an object travels. Speed is calculated by dividing the
distance traveled by the time elapsed. |
|
square
| |
A shape with four equal angles and four equal sides.
|
|
temperature
| |
A measurement of the hotness or coldness of an object.
|
|
volume
| |
A measurement of the amount of space contained within a three-dimensional shape.
|
|
weight
| |
A measurement of the gravitational pull on an object on the earth's
surface. Weight is expressed in English units. In the shop, weight and
mass are used interchangeably. |
