ENGINEERING MEASUREMENTS
What is a “MEASUREMENT”? The word “measurement” comes from the Greek word “metron,” which means
“limited proportion.” Measuring is the act of determining a target's size, length, amount volume, weight,
capacity, or other aspect with an instrument marked in standard units.
Or-The assignment of a numerical value to an object’s physical property.
What is a Standard Unit?
➢Metric system: millimeter, centimeter, meter, kilometer, liter, gram, Celsius..
➢Imperial system: inch, foot, yard, mile, gallon, pounds, Fahrenheit..
Why are measurements important? Measurements are used to quantify properties of everything around us!
How difficult would it be to describe how hot or cold it is with our the use of degrees?
How difficult would it be to buy clothes and shoes with out sizes?
How difficult would it be for an Engineer to have a product made if there was no way to communicate what size
it needs to be?
Activity
Measure your part to their corresponding highlight engineering drawing dimensions.
Determine which measurement method is best for the highlighted dimension. Use the
measurement log to collect your data. Refer to the measurement guides for instruction on
how to use the available measurement methods.
Level 2
For applicable measurement types try measuring the same feature on a part with the ruler and
the caliper.
Do you measure the same value with both methods?
Which method has a higher resolution?
Level 3
Measure your parts using blocks: Place the part on the sheet and count the number of blocks
to measure the height of a Sensata Part. Try measuring three different parts.
