1.
Convert 55 mm into inches.
Locate the number 50 in the vertical column at the left side, take this as
(1)
line from
.
Locate the number 5in the row across the top, take this as
(2)
down from
.
Take the point where the two lines cross as
(3)
from millimeters to inches. Therefore, 55 mm = 2.165 inches.
Convert 550 mm into inches.
2.
The number 550 does not appear in the table, so divide by 10 (move the decimal point one place
(1)
to the left) to convert it to 55 mm.
Carry out the same procedure as above to convert 55 mm to 2.165 inches.
(2)
The original value (550 mm) was divided by 10, so multiply 2.165 inches by 10 (move the decimal
(3)
point one place to the right) to return to the original value.
This gives 550 mm = 21.65 inches.
