| Reef Sanctuary's Mr. Wizard   | The Units of Reefkeeping: help needed We are putting together a list of names/units of measuremnet for Randy's new upcoming artilce He is thinking of an encyclopedic listing of units, with definitions and some conversions. We need to collect all the units that folks encounter (within reason). So please add any onto this thread to make it as complete as possible. I will then drop them over to Randy to add to this list if they fit right. Here's the list update so far, as info comes in. absorbance alkalinity amp (ampere) Angstrom atm (atmosphere; pressure) bar BTU (British Thermal Unit) calorie candle (light) candela cm (centimeter) CRI (color rendering index) cubic foot cup cycles per second dB (decibel; sound) dKH degree Fahrenheit degree Celsius drop erg farad (F; capacitance) faraday (Fd; electric charge) fluid ounce foot foot candles grain/gallon g (gram) g/L (gram/liter) g/ml (gram per milliter; density) gallon GPH (gallons per hour) GPM (gallons per minute) GH (general hardness) gram equivalent weight horsepower hour Hz (Hertz) Imperial gallon inch Iodine number (mg/g) ionic strength (mole/kg or mole/L) J (Joule) K (Kelvin temperature) K (Kelvin color temperature) kcal (kilocalorie) kg (kilogram) kPa (kiloPascal) kW (kilowatt) kWh (kilowatt hour) L (liter) LPH (liters per hour) lumen (lm) lumen/watt lux (lm/m2) meter mho uE (microEinstein = 6.022*1017 photons; Flux density (PPFD)) uE/s*m2 (microEinstein/m2/second; PAR) um (micrometer; micron) uM (micromolar) micron meq/L (milliequivalents per L; usually alkalinity) meq/L/pH unit (buffering capacity) mm (millimeter) mg/kg (milligram per kilogram) mg/L (milligram per liter) mS/cm (milliSiemen per centimeter; conductivity) mV (milliVolt) mL (milliliter) mM (millimolar) minute molal (mole/kg) M (molar) molasses number mole fraction N (normal) osmolarity (mole/L or mole/kg) ounce nm (nanometer) nM (nanomolar) Ohm ORP Pa (pascal) pH ppb (parts per billion) ppm (part per million) ppm calcium carbonate equivalents ppm-C (part per million carbon) ppm-N (part per million nitrogen) ppm-P (part per million phosphorus) ppm TDS ((part per million total dissolved solids) ppt or ppth (parts per thousand) ppt (parts per trillion) percent relative humidity percent solution pint psi (pounds per square inch) psig (pounds per square inch gauge) power factor PSU (practical salinity units) quart refractive index second S (salinity) S/cm (Seimen per centimeter; conductivity) specific gravity steradian tablespoon teaspoon torr TDS (total dissolved solids) transmission volt (V) volt ampere (VA) watt Watt/m2 (Spectral irradiance) wavelength weight percent

| Reef Sanctuary's Mr. Wizard | It started about a month ago when some asked something and I did some conversions, IIRC, NO3-N vs NO3 and Randy said hey maybe I should just do an article on that....conversions and the likes...I said yah, I 'm getting tierd of explaining things like meq and what it means . He started it much quicker than I thought He has been heckling me though for some that I have dropped " Does anyone bring those up besides you? "  Michelle That is not the first one we have been asleep on
