Usage of fractions is recommended when more precision is needed. If we want to calculate how many Inches are 1.5 Millimeters we have to multiply 1.5 by 5 and divide the product by 127. So for 1.5 we have: (1.5 × 5) ÷ 127 = 7.5 ÷ 127 = 0.059055118110236 Inches. So finally 1.5 mm = 0.059055118110236 in.
