I am Trudy-Ann and I am presently perusing my Degree in Mathematics. Being a teacher of Mathematics, it gives me great joy to impart the knowledge which I have gained, to individuals who I come in contact with.

Measurements

Measurement is the process observing and recording the observations that are collected as part of a research effort.

'''Types of Measurements'''

Units tell us two important things about the object being measured—what is being measured and its size. Measurement is categorized according to capacity, weight, length, or temperature, and how big, heavy, long, or hot is the object. Each type of measurement must have an appropriate unit of measurement associated with it. For example, the basic unit of measure for weight is gram, basic unit of measure for capacity is liters, the basic measure for temperature is degree Celsius or degrees Fahrenheit and the basic unit for the measure of length is meter.

'''Measurements associated with the Imperial Measurement System'''

'''Units of Length'''

1 foot (ft.) = 12 inches (in.)

1 yard (yd.) = 3 feet = 36 inches

1 mile (mi.) = 1,760 yards = 5,280 feet

1 square foot (ft.2) = 144 square inches (in.2)

1 square yard (yd.2) = 9 square feet

1 square mile (mi.2) = 640 acres = 3,097,600 square yards

1 acre (A) = 4,840 square yards = 43,560 square feet

1 cubic foot (ft.3) = 1,728 cubic inches (in.3) ≈* 7.48 gallons

1 cubic yard (yd.3) = 27 cubic feet

'''Units of Volume'''

1 tablespoon (tbs.) = 0.5 fluid ounce (fl. oz.)**

1 tablespoon = 3 teaspoons (tsp.)

1 cup (c.) = 8 fluid ounces

1 pint (pt.) = 2 cups = 16 fluid ounces

1 quart (qt.) = 2 pints = 32 fluid ounces

1 gallon (gal.) = 4 quarts = 128 fluid ounces

1 gallon ≈* 231 cubic inches ≈* 0.1337 cubic foot

'''Units of Weight'''

1 pound (lb.) = 16 ounces (oz.)**

1 ton (T) = 2,000 pounds

* The symbol ≈means about equal to.

** Notice that ounces are used to measure the dimensions of both volume and weight.

'''Standard Units of Time'''

Measurement of time has historically been based on the movement of the Sun. Shorter intervals were measured by physiological periods such as drawing breath, winking or the pulse.

As technology upgrades time is now measured using the 12 hour clock and the 24 hour clock. The 24 hour clock uses four digits.

1 minute (min.) = 60 seconds (sec.)

1 hour (hr.) = 60 minutes

1 day = 24 hours

1 week = 7 days

1 year (yr.) = 52 weeks

1 year = 12 months

1 year = 365 days

Metric System 

The major system of measurement is the metric system. The basic units of the metric system are the meter, gram, and liter.

'''Units of Length'''

1 centimeter (cm) = 10 millimeters (mm)

1 meter (m) = 100 centimeters = 1,000 millimeters

1 kilometer (km) = 1,000 meters

1 square centimeter (cm2) = 100 square millimeters(mm2)

1 square meter (m2) = 10,000 square centimeters = 1,000,000 square millimeters

1 square kilometer (km2) = 1,000,000 square meters

1 cubic centimeter (cm3) = 1,000 cubic millimeters (mm3)

1 cubic meter (m3) = 1,000,000 cubic centimeters

Temperature

Temperature can be defined by how hot or cold something is. One of the most common devices for measuring temperature is the glass thermometer. This consists of a glass tube filled with mercury or some other liquid, which acts as the working fluid. Temperature increase causes the fluid to expand, so the temperature can be determined by measuring the volume of the fluid. Such thermometers are usually calibrated so that one can read the temperature simply by observing the level of the fluid in the thermometer. Another type of thermometer that is not really used much in practice, but is important from a theoretical standpoint, is the gas thermometer.

Other important devices for measuring temperature include:

(RTD) probes (for electron temperature of a plasma)
 * Thermocouples
 * Thermistors
 * Resistance temperature detector
 * Pyrometer
 * Langmuir
 * Infrared
