hr will all be accepted in the Convert command for Watt-hours.The Convert routine will accept a hyphen (-), a space or character 250 ( Other useful characters are Alt-248 which displays the degree symbol and Alt-250 which appears as a dot ( Let the Alt key up and the µ should appear. To enter µ as in µm, hold the Alt-Key down and type 230 on the numeric keypad. The Convert function should be used in preference to constants that have inherent dimensions (e.g., 144 in^2/ft^2) in order to avoid false error reports from the Check Units command. Instructions for entering new units are provided in the UNITS.TXT file. If you find that a unit you need is not defined, you can enter it by editing the UNITS.TXT file in the EES directory. The defined unit symbols can be displayed with the Unit Conversion Info in the Options menu. Groups of units contained in parentheses can be raised to a power as in the following conversion. Terms are separated with an optional * symbol or with a / symbol, as in the example below. Each term is enclosed within parentheses. The Convert function will accept multiple unit terms. The following example converts 5 Btu/hr-ft^2-R into W/m2-K and sets H equal to this number: The ^ symbol is optional so ft2 and ft^2 are equivalent. See Entering Units for detailed information. All units to the right of the division symbol are assumed to be in the denominator (i.e., raised to a negative power). Only one division symbol may be used in any one term. In a combination of units, such as Btu/hr-ft^2-R, the individual units are separated with a space, a hyphen (i.e., -), a dot ( Will set FI to a value of 144 because 1 square foot is 144 square inches.Ĭombination of units and multiple unit terms may be entered. The Convert function returns the value X which satisfies the following relation: (Note: use a semicolon instead of a comma as the list separator when using the European numerical format) Use the CONVERTTEMP function for this purpose. NOTE: The CONVERT function will convert temperature differences but it does NOT convert temperatures from one scale to another. The unit designations can be optionally enclosed in square brackets. String variables are identified with a $ as the final character in the variable name. If string constants are used, the single quote marks are optional. Where From and To are unit designations provided either as string constants or string variables. The Convert function provides unit conversions.
