Method of using the Conversion Table to convert from millimeters to inches
1.
Convert 55 mm into inches
A. Locate the number 50 in the vertical column at the left side, take this as
b
, then draw a horizontal line from
b
.
B. Locate the number 5 in the row across the top, take this as
c
, then draw a perpendicular line down from
c
.
C. Take the point where the two lines cross as
d
. This point
d
gives the value when converting from millimeters to
inches. Therefore, 55 millimeters = 2.165 inches.
2.
Convert 550 mm into inches
A. The number 550 does not appear in the table, so divide by 10 (move the decimal one place to the left) to convert it to
55 mm.
B. Carry out the same procedure as above to convert 55 mm to 2.165 inches.
C. The original value (550 mm) was divided by 10, so multiply 2.165 inches by 10 (move the decimal one place to the
right) to return to the original value. This gives 550 mm = 21.65 inches.
