Measuring Tools

An anemometer or windmeter is the device that measures wind speed. They are usually divided into those that measure the wind's speed and it's pressure. The first known anemometer was described in 1450 by Leon Battista Alberti. anemometer. ...

The instrument used to measure electrical current is called an ammeter, which is actually a shortened form of 'amp meter'. The current is measured in amperes. In scientific labs, a much more sensitive instrument called a galvanometer is used to measure very small currents. ...

The least count of the vernier can be measured by using the formula stated below. Least count (L.C) = 1 M.S.D - 1 V.S.D Example; vernier scale is constructed by taking 49 main scale divisions dividing them into 50 divisions ie. 49mm divided into 50 parts therfore 1 vsd=49/50 mm=0.98mm 1 MSD=1mm substituting in formula L.C = 1 M.S.D - 1 V.S.D L.C=1-0.98=0.02mm ...

There are 1000000 micrometers in a meter Answer is 451 +++ They have a name of their own: "micron", but the standard ISO symbol is the abbreviation for micro-metre formed by prefixing the letter 'm' with the Greek letter lower-case 'mu'. Thus: µm (I had to copy that from 'Word' because Answers seems not to have a symbol set. You may also find mu by the key combination ALT+0181.) A micrometer is a measuring device. ...

Hi, heres how you calculate least count of a micrometer. Use the given formula: Least Count (L. C) = Pitch/no. of divisions on micrometer barrel(thimble) where, Pitch = distance travelled by thimble on linear scale in one rotation. Hi, heres how you calculate least count of a micrometer.

The Greeks had simple thermometers in the first century BC. Galileo Galilei (1564-1642) Italian physicist, invented a basic air thermometer. Daniel Gabriel Fahrenheit (1686-1736) was the German physicist who invented the alcohol thermometer in 1709, and the mercury thermometer in 1714. In 1724, he introduced the temperature scale that bears his name - Fahrenheit Scale. The Celsius scale, invented by Swedish Astronomer Anders Celsius (1701-1744), has 100 degrees between the freezing point (0 C) and boiling point (100 C) of pure water at sea...

A digital micrometer is used exactly the same way as a standard micrometer. The only difference is the way the measurement are viewed. Here are the steps to follow for using a digital outside micrometer: Clean the anvil and spindle faces. Push the "On/Off" or any other button on some and turn it on. Use a test piece (supplied with the micrometer) and close the micrometer on it using the ratchet on the back of the thimble. Push the "Zero" or "Reset" but to...

A micrometer (device) measures distance more accurately with more precision than a vernier or a tape measure. It is much cheaper than using an electron microscope, which can measure, with calibration, a length in the order of 1E-9 meter. A micrometer (unit) is equal to 1E-6 meter. ...

Irregular objects can be volumetrically measured with three simple tools; a scale, a container large enough to contain the entire object, and enough water to fill the container. If you fill the container with water and weigh it, fully submerge the object in the water and remove it, compare the final mass of the container and water to the container full of water, the difference between the two in grams is the same as the volume of the object in cubic centimeters. ...

The least count of micrometer is 0.01mm and it is very important in the physics labs and sometimes also in biology labs. The observations with these instruments should be very carefully and precisely carried out because chances of human error are high. it is calculated as: least count = pitch of screw/ no. of divisions on circular scale ...

An amp meter can measure the intensity of electric current.

Standard is 0.01 mm

A vernier caliper is a measuring tool used in science for making extremely precise measurements. There is a pair of "jaws" that collapse around an object to be measured. The boldface numbers on the fixed scale are in centimeters, and the tick marks between the boldface numbers are in millimeters. The left-most tick on the sliding part of the scale will allow you to read from the fixed scale the number of whole millimeters that the jaws are opened. The vernier caliper...
