-Process of comparing an object’s physical quantities using a standard measuring device.
-It involves numbers accompanied by the appropriate unit of measurement.
Units of Measurement
-Identifies the physical quantity being measured by the measuring device.
All systems of weights measure, metric and non-metric, are linked through a network of International System is called the SI, using the first two initials of its French name Systeme Intenational d'Unites.
S.I Base Units
Physical Quantity
- Length (m)
- Mass (kg)
- Time (s)
- Amount of Substance (mol)
- Thermodynamic Temperature (K)
- Electric Current (A)
- Luminous Intensity (cd)
Non - S.I. Base Units
- Time(min, hr, d)
- Volume (L, ml)
- Density (g, ml)
- Thermodynamic Temperature
- Pressure (C)
- Energy
Calibrations
-Lines and number found on a measuring device that represents place values.
-Each segment ID divided into 10 equal parts and was patterned after the metric system of measurement.
Accuracy
-Place value usually represented by the smallest lines on the measuring device and is the smallest value represented by the measuring device's calibration.
Sensitivity
-The estimates, approximated place value after accuracy.
Place Values
-In our decimal number system, the value of a digit depends on its place, or position, in the number. Each has a value of 10 times the place to its right.
Number in standard form is separated into groups of three digits using commas. Each of these groups is called period.
Numbers, such as 84, have two digits. Each digit is a different place value.
The left digit is the tens' place. It tells you that there are 8 tens.
The last or right is the ones' place which is 4 in this example. Therefore, there are 8 sets of 10, plus 4 ones in the number 84.
8 4
| |_____ ones' place
| __________ tens' place
