The Fahrenheit scale is not absolute and also is obsolete.The absolute scale is Kelvin.
The Fahrenheit scale has 180 divisions or degrees
16 degrees Celsius is equivalent to 60.8 degrees Fahrenheit on the Fahrenheit scale.
27° Celsius = 80.6° Fahrenheit.
Anders Celsius created the Celsius scale in 1742, and Daniel Gabriel Fahrenheit developed the Fahrenheit scale in 1724.
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
Least count of voltmeter is the value of one division on the scale. Formula is: Least count = Range/No. of divisions For example, if a voltmeter can measure from 0 to 40 V, and it has 100 divisions in total on the scale, then its least count is 40/100 = 0.4V
