The Fahrenheit absolute scale is called the Rankine scale. It is used in engineering and some scientific fields as an alternative to the Celsius and Fahrenheit scales.
The Fahrenheit scale has 180 divisions between the freezing point and boiling point of water.
16 degrees Celsius is equivalent to 60.8 degrees Fahrenheit on the Fahrenheit scale.
The Fahrenheit scale was named after its inventor, Daniel Gabriel Fahrenheit, a physicist and engineer who created the temperature scale in the early 18th century.
27°C is equal to 80.6°F on the Fahrenheit scale.
least count of scale is 1mm
first find out least count of main circular scale in degrees,then divide least count of main scale by total divisions on cylindrical scale(this cylindrical scale works as vernier scale for fist one,its least count will be in minutes) then further divide least count of cylindrical scale by total divisions of small vernier scale which touches it,(this small scale works as vernier scale for cylindrical scale and its least count will be in seconds).
The least count of a wall thermometer is typically 1 degree Celsius or Fahrenheit, depending on the scale used. This means that the thermometer can measure temperature changes in increments of 1 degree.
least count of a micrometer= pitch/no of division on the circular scale
The least count of a half meter scale is 0.5 cm. This means that the smallest measurement that can be accurately obtained using the scale is 0.5 cm.
The least count of a physical balance is the smallest measurement that can be read or displayed on the balance scale. It is determined by the precision of the scale and the smallest division marked on the scale or indicated by the scale's display.
The least count of a screw gauge is calculated by dividing the pitch of the screw by the number of divisions on the circular scale. The formula is Least Count = Pitch / Number of divisions on the circular scale.
The least count of a thermometer scale is the smallest temperature difference that can be measured by the scale. It is typically based on the precision of the markings on the scale, which can vary depending on the design and calibration of the thermometer.
The least count of a vernier scale is the smallest measurement that can be read or determined on the main scale. It is calculated by dividing the smallest division on the main scale by the total number of divisions on the vernier scale. A smaller least count allows for more precise measurements to be taken.
Doubling the number of divisions on the circular scale of a spherometer will decrease the least count by half. The least count is inversely proportional to the number of divisions, so as the number of divisions increases, the least count decreases.
The formula to calculate the least count of a micrometer is: Least count = Pitch of screw gauge / Number of divisions on circular scale
To find the least count of a voltmeter or ammeter, you need to divide the smallest division on the scale by the number of divisions per scale unit. For example, if the smallest division on the scale of a voltmeter is 0.1 V and there are 10 divisions per scale unit, then the least count would be 0.01 V.
