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

Method of using the Conversion Table to convert from millimeters to inches

Convert 55

into inches.

Locate the number 50

the vertical column at the left side, take this as

ⓐ

, then draw a

horizontal line from

ⓐ

Locate the number 5

the row across the top, take this as

ⓑ

, then draw a perpendicular line

down from

ⓑ

Take the point where the two lines cross as

ⓒ

. This point

ⓒ

gives the value when converting

from millimeters to inches. Therefore, 55

= 2.165 inches.

Convert 550

into inches.

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 55

Carry out the same procedure as above to convert 55 mm to 2.165 inches.

The original value (550

) 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 550

= 21.65 inches.
