| measures of water volume and water flow | |
| Acre | A measure of area. There are 43,560 square feet in an acre. |
| AF (Acre Foot) | A measure of volume. For example one acre-foot of water is the volume of water needed to cover one acre to a depth of one foot. |
| MAF/year (Million Acre-Feet per Year) |
A measure of flow in which 1 million acre-feet of water passes a measuring point in a year. |
| TCFS (Thousand Cubic Feet per Second) |
A commonly used measure of water flow in which one thousand cubic feet passes a measuring point in a second. To covert from MAF/year to TCFS, multiply by 1.38. For example, a flow of 10 MAF/year corresponds to a flow of 13.8 TCFS or 13,800 cubic feet per second. |
| measures of electric energy and electric power | |
| Kilowatt-hour (kwhr) | A measure of electric energy. One kwhr of energy is the same as 3,414 BTUs, where a BTU is a British Thermal Unit. |
| Kilowatt (kw) | A measure of electric power. If 1 kw of power is sustained over one hour, the delivered energy would be 1 kwhr. |
| Megawatt (MW) | A measure of electric power. There are 1,000 kw in a MW. |
| Average MW (aMW) | A measure of electric energy. If you maintain 1 MW of power over an entire year, the delivered energy would be 1 aMW. Since there are 8,760 hours in a year, one aMW corresponds to 8.76 million kwhrs of electric energy. |
| economic and agricultural measures | |
| mills/kwhr | The units commonly used to value electric energy. There are 1,000 mills in a dollar. So a value of 30 mills/kwhr corresponds to a value of 3 cents per kilowatthour. |
| Bushel (bu) | A bushel is the measure of volume normally used to measure wheat. One bushel corresponds to 1.24 cubic feet. |
| Ton | A ton is the measure of weight normally used to measure alfalfa. One ton corresponds to 2,000 pounds. |
| Dollars ($) | Prices are expressed in constant, US dollars. For example, the price of wheat is in $/bu or dollars per bushel. The Idagon Economic Product (IEP) is expresed in constant, US dollars. |
| Hundred Weight (cwt): | Potato production is normally measured in hundred weight where 1 cwt corresponds to a one hundred pound sack of potatos. |
