3. CONVERSION TABLE
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
Example
Method of using the Conversion Table to convert from millimeters to inches
Method of using the Conversion Table to convert from millimeters to inches
Convert 55
mm into inches.
Locate the number 50
in the vertical column at the left side, take this as ⓐ , then draw a
horizontal line from
ⓐ .
Locate the number 5
in 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
mm = 2.165 inches.
Convert 550
mm 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
mm .
Carry out the same procedure as above to convert 55mm to 2.165 inches.
The original value(550
mm ) 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
mm = 21.65 inches.
