Solved Least Count And Instrument Uncertainty The Least Chegg Least count is the smallest measurement that a measuring instrument can provide with accuracy. all readings or measured values from an instrument are good only up to this measure, i.e., the least count. the least count of a measuring instrument is inversely proportional to its precision value. Mathematically a measurement instrument least count is calculated by dividing main scale reading by the total number of divisions on the main scale. and if the instrument also has a secondary scale. then instrument lc is the ratio of main scale l.c. and number of divisions on the secondary scale.
How To Calculate Least Count Laxenbank The least count of a measuring instrument can be calculated by dividing the range of the scale by the number of divisions on the scale. for example, if a ruler has a range of 10 centimeters and has 100 divisions on the scale, its least count will be 0.1 centimeters. Least count is calculated by taking a known interval and dividing by the number of divisions. least count = known interval number of division. in the case of the ruler above, in each 1 inch interval there are eight divisions. this means that the least count of the inch ruler is 1 8”. Least count is the smallest value any instrument can read or measure. you may hear of vernier caliper of least count 0.02 mm, which means the minimum value vernier can measure is 0.02 mm. you can’t measure a value less than 0.02 mm with this vernier calliper. The least count of a measuring instrument can be mathematically determined by dividing the main scale reading by the total number of divisions on the main scale. in the event that the instrument also features a secondary scale, the least count is determined by the ratio of the main scale least count and the number of divisions on the secondary.

Calculating the least count of an instrument is essential to determine its precision and accuracy. by following the steps mentioned above, one can easily calculate the least count. it is crucial to consider the scale and the smallest division on that scale to derive the least count accurately. To calculate the least count of an instrument, you need to consider the smallest division or increment on its scale. the least count is found by dividing the value of one division of the main scale by the total number of subdivisions on the auxiliary scale or vernier scale, if applicable. Using an instrument, one can not precisely measure a quantity smaller than the least count of that instrument. examples: if a meter scale has millimeter divisions on it, the least count is 1 mm (so, one can't measure a length shorter than 1 mm from this scale). The least count of an instrument is inversely proportional to the precision of the instrument. for example, a sundial might only have scale marks representing hours, not minutes; it would have a least count of one hour.
