This week we learnt how to read a micrometer in metric units. First you have to figure out what number is on the horizontal line. Each indent represents .50mm so in this picture, the total is 1.5mm. Then you have to read the vertical line which goes up by .01mm. In this picture it reads to .49mm. Then you add both numbers up so 1.5+.49 which equals to 1.99mm.
