How to Read Micrometer Screw Measurements


Micrometer Screw with main scale in millimetres with a precision scale 0.01 mm


Example 1
Main Scale = 2,5 mm

Thimble Scale = 12 multiplied by the scale of precision

= 12 x 0,01 mm

= 0,12 mm



Result = Main Scale + Thimble Scale

= 2,5 mm + 0,12 mm
2,5 12
= 2,62 mm

Example 2
Main Scale = 8 mm

Thimble Scale = 16 multiplied by the scale of precision

= 16 x 0,01 mm

= 0,16 mm



Result = Main Scale + Thimble Scale

= 8 mm + 0,16 mm

= 8,16 mm

8 16


Example 3


Main Scale = 2,5 mm

Thimble Scale = 35 multiplied by the scale of precision
8
= 35 x 0,01 mm

= 0,35 mm



Result = Main Scale + Thimble Scale

= 2,5 mm + 0,35 mm

35 = 2,85 mm
2,5
