Desk rulers are used for three main purposes: to measure, to aid in drawing straight lines, and as a straight guide for cutting and scoring with a blade. Practical rulers have distance markings along their edges.

These are the best rulers for precision and accuracy in your blueprints, floor plans, and geometric works on paper.

The two units of measurement most commonly used for typesetting and design are points and picas.

30 cm

In typography, one of several different types of instruments used to measure points and picas. Also called a line gauge or an E-gauge (when the letter “E” is shown in several labeled sizes, for comparison to a printed type sample).

Description of Measuring Instruments – The most commonly used device to measure gauge pressure is a Bourdon tube pressure gauge. It is a mechanical device which consists of a tube formed into a C-shape and sealed at one end.

Gauge is an inspection tool used to check product dimension with reference to it’s maximum and minimum acceptable limit. It is generally used to segregate acceptable and non acceptable product in mass production, without knowing exact value of dimension. 3.

Measuring Tools

- Tape Measures.
- Stainless Steel Rules.
- Straight Edge Tools.
- Damp Meters.
- Telescopic Measuring Rods.
- Angle Finders.
- Leica Disto – Laser Meter.
- Squares.

Here are some most commonly used mechanical instruments for measurement in industries….

- Vernier Caliper.
- Micrometer.
- Steel Scale.
- Vernier Height Gauge.
- Vernier Depth Gauge.
- Bevel Protractor.
- Dial Gauge (Plunger, Level)

The three measures are descriptive, diagnostic, and predictive. Descriptive is the most basic form of measurement.

General Least Count Formula

- Formula: 1.
- Least Count = Value of 1 main scale division / Total main scale divisions.
- Formula: 2.
- Least Count of main scale = Value of 1 main scale division / Total main scale divisions.
- Least Count Of Secondary Scale = Value of 1 secondary scale division / Total secondary scale divisions.

0.02

The Vernier caliper least counts formula is calculated by dividing the smallest reading of the main scale with the total number of divisions of the vernier scale.LC of vernier caliper is the difference between one smallest reading of the main scale and one smallest reading of vernier scale which is 0.1 mm 0r 0.01 cm.

The LC of vernier calliper is the difference between one smallest main scale reading and one smallest vernier scale reading of 0.1 mm 0r 0.01 cm. The Least Count measuring instrument is determined mathematically by calculating the main scale reading by the cumulative number of divisions on the main scale.

In the science of measurement, the least count of a measuring instrument is the smallest and accurate value in the measured quantity that can be resolved on the instrument’s scale. The least count of an instrument is inversely proportional to the precision of the instrument.
