METRIC SYSTEM
Typically, scientific reports use metric units; therefore, this
eis presents metric units of measure (meters, liters, grams,
etc.) rather than the more common U.S. Customary Units (feet,
gallons, pounds, etc.). However, the text sections also provide
U.S. Customary Units in parentheses for ease of understanding.
Many metric measurements presented include prefixes that denote a
multiplication factor that is applied to the base standard (e.g.,
1 kilometer = 1,000 meters). The following list presents these
metric prefixes:
mega 1,000,000 (l06; one million)
kilo l,000 (103; one thousand)
hecto 100 (102; one hundred)
centi 0.01 (10-2; one one-hundredth)
milli 0.001 (10-3; one one-thousandth)
micro 0.000001 (10-6; one one-millionth)
nano 0.000000001 (10-9; one one-billionth)
pico 0.00000000001 (10-12; one one-quadrillionth)
DOE Order 5900.2A, "Use of the Metric System of Measurement"
(3/26/92) prescribes the use of this system in DOE documents.
The following list presents conversion factors for the metric
units used in this eis as an aid to readers who are more familiar
with U.S. Customary Units.
Conversion from Metric to U.S. Customary Units
1 meter = 3.281 feet = 39.37 inches = 1.094 yards
1 kilometer = 0.6214 mile
1 square meter = 10.764 square feet
1 square kilometer = 0.3861 square mile = 247.1 acres
1 liter = 61.025 cubic inches = 0.2642 gallon
1 cubic meter = 35.31 cubic feet = 1.308 cubic yards = 264.2 gallons
Discharge
1 cubic meter per second = 35.31 cubic feet per second = 15,850.3
gallons per minute
Mass
1 kilogram = 2.205 pounds (mass)
1 metric ton = 2,205 pounds = 1.1023 (short) tons
Pressure
1 Pascal = 0.02089 pound per square foot
1 kilogram (force) per square meter = 0.2048 pound (force) per square foot
Velocity
1 meter per second = 3.281 feet per second = 2.237 miles per
hour
1 kilometer per hour = 0.6214 mile per hour
Temperature
-C to -F, -C - 1.8 + 32 (i.e., 20-C = 20 - 1.8 + 32 = 68-F)
