Stage micrometer with two scales on it - 1" and 25mm.

• 1" ruler is numbered .0 through 1.0 every .100" division
• 0.0" through 1.0" divided into 0.1" increments
• 0.9" through 1.0" divided into 0.01" increments
• The last two 0.01" increments are divided into 0.001" increments
  
• 25mm rulers is equally spaced and numbered 0 through 25
• Each division between numbers 0 through 25 = 1.0mm
• Each division between numbers 20 through 23 = 0.1mm
• Each division between numbers 23 through 25 = .02mm
