Vernier calipers are used to measure length when quite accurate measurement is required, but not such accuracy as to require a micrometer.
micro meter least count in British system
It is less than a micrometer but greater than a non vernier caliper or ruler.
My mooom and the advantage in meausurung with vernier caliper and the micro meter is grams mass length volume and all that measuring stuff
A rulerDepending on the degree of accuracy required: a ruler, vernier callipers, micrometer.
It is the scale on a micrometer.
*Micrometer have a rotary handle and whereas vernier have a slider. *Micrometer is for measuring diameters while vernier is for measuring inside & outside diameter as well as depth. *Least Count of Vernier Caliper is 0.02mm *Least Count of Micrometer is 0.01mm
With a Vernier or Micrometer.

The zero error in the vernier calipers and micrometer screw gauge when the O mark on the main scale is not in line with the pointer.
micrometer is more occurate.
Micrometer or vernier caliper
.001
LC FOR VERNIER CALIPER-0.1mm LC FOR MICROMETER -0.01 mm L.C- NO OF SMALLEST DIVISION ON MAIN SCALE ------------------------------------------------------- TOTAL NO OF DIVISION ON VERNIER SCALE
Standard is 0.01 mm
In case for micrometer, principle of pitch is used. Least count could be even micro meter But in vernier caliper, difference of main scale division and vernier scale division is the principle Least count could be 0.02 mm
The most compelling reason to select the micrometer Screw over the Vernier caliper is the guarantee that when measuring a flexible surface, the same amount of pressure is applied between samples. The Vernier caliper has the ability to measure internal and externally, but if precision is required, the micrometer screw is the tool of choice.
