Basic conversions Complete the table below Example 1 Example 2 Convert 2350nm Convert 143mm 2350nm 1000 = m 143mm x 1000 = 143,000 m m 1000 = 143,000 m x 1000 = 143,000,000nm Millimetre Micrometre Nanometre 1580 174 3 18 23 8 5 Page 2 of 12 2. The equation triangle This equation triangle gives you 3 equations. What are they? Image = Actual = Magnification = Basic calculations 1. A human hair is 25 m and is observed at x400.
