SI to Inch/Pound

Multiply	By	To obtain
micron (µm)	0.00003937	inch (in.)
millimeter (mm)	0.03937	inch (in.)
meter (m)	3.281	foot (ft)
square meter (m2)	1,550.0	square inch (in2)
gram (g)	0.03527	ounce, avoirdupois (oz)
kilogram (kg)	2.205	pound avoirdupois (lb)
liter (L)	33.82	ounce, fluid (fl oz)
liter (L)	0.2642	gallon (gal)
milliliter (mL)	0.03382	ounce, fluid (fl oz)
liter (L)	61.02	cubic inch (in3)
cubic meter (m3)	35.31	cubic foot (ft3)
cubic meter (m3)	264.2	gallon (gal)
milligram per liter (mg/L)	1.0	parts per million (ppm)
Watt (W)	3.41	British thermal unit per hour (BTU/h)

Temperature in degrees Celsius (°C) may be converted to degrees Fahrenheit (°F) as follows:


°F=(1.8×°C)+32.


Concentrations of chemical constituents in water are given either in milligrams per liter (mg/L), which is approximately equivalent to parts per million (ppm), or micrograms per liter (µg/L), which is approximately equivalent to parts per billion (ppb).


Datums


Elevation refers to distance above the vertical datum. A local vertical datum (UKLVD) is used, established by the Bureau of Reclamation. For the purpose of this report, the conversion is UKLVD – 1.78 ft = NGVD29.


Horizontal coordinate information is referenced to the North American Datum of 1983 (NAD 83).
