The least count of a barometer refers to the smallest increment that can be measured by the device, typically indicating changes in atmospheric pressure. For standard Mercury barometers, the least count is usually around 0.1 mm of mercury (Hg), while aneroid barometers may have a least count of 0.1 to 0.5 hPa (hectopascals). This precision allows for accurate readings of atmospheric pressure, which is essential for weather forecasting and altitude measurement.

What is an aneroid barometer called?
Well, an aneroid barometer, is called an aneroid barometer- but, a barometer measures air pressure, and an aneroid barometer is a barometer that contains no liquid.
How do you find least count?
To find the least count of an instrument or measuring device, divide the smallest measurement unit by the total number of divisions on the scale. The least count represents the smallest increment that can be measured or displayed by the instrument.
What is the least count of an analytical balance?
least count of a spectrometer is equal to 1' (one minute)
How do you calculate readings of sextant?
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).
Definition of least count of screw gauge?
The least count of a screw gauge is the smallest measurement that can be read or determined using the instrument. It is essentially the smallest change in the position of the thimble that can be detected, which corresponds to the smallest change in the measured dimension.

Why is barometer useful?
Because it has a high density... meaning that the volume increase or decrease due to altitude change is can be viewed in a practical sized barometer. If water, which had a much lower density, was used instead of Mercury, the barometer must be at least 15m high.
How do you calculate least count of digital micrometer?

What is formula to calculate least count of micrometer?
The formula to calculate the least count of a micrometer is: Least count = Pitch of screw gauge / Number of divisions on circular scale

What is least count for thermometer?
The least count of a thermometer is the smallest temperature difference that it can measure accurately. Typically, for a standard mercury-in-glass thermometer, the least count is 0.1°C.
