can occur.

Unit Conversion Tables for Lengths & Distances
A note on the metric system:
Before you use this table, convert to the base measurement first, in that convert centi-meters to
meters, convert kilo-grams to grams. In this way, I don't have to list every imaginable
combination of metric units.
The notation 1.23E
+ 4
stands for 1.23 x 10
+4
= 0.000123.

To use: Find the unit to convert
from
in the left column, and multiply it by the expression under
the unit to convert
to.
Examples: foot = 12 inches; 2 feet = 2x12 inches.
Useful Exact Length Relationships
mile = 1760 yards = 5280 feet
yard = 3 feet = 36 inches
foot = 12 inches
inch = 2.54 centimeters
