0-3 87728465 NA Issued 03-2008 Bur SECTION 0 - FOREWORD 3. CONVERSION TABLE Method of using the Conversion Table. The Conversion Table in this section is provided to enable simple conversion of figures. For details of the method of using the Conversion Table, see the example given below. Example 1. Method of using the Conversion Table to convert from millimeters to inches. Convert 55mm into inches. (1) Locate the number 50 in the vertical column at the left side, take this as ’a’, then draw a horizontal line from ’a’. (2) Locate the number 5 in the row across the top, take this as ’b’, then draw a perpendicular line down from ’b’. (3) Take the point where the two lines cross as ’c’. This point ’c’ gives the value when converting from millimeters to inches. Therefore, 55mm = 2.165 inches. 2. Convert 550mm into inches. (1) The number 550 does not appear in the table, so divide by 10 (Move the decimal point one place to the left) to convert it to 55mm. (2) Carry out the same procedure as above to convert 55mm to 2.165 inches. (3) The original value (550mm) was divided by 10, so multiply 2.165 inches by 10 (Move the decimal point one place to the right) to return to the original value. This gives 550mm = 21.65 inches.
