CONCURVE (free with any order)
This system contains two very powerful and useful programs  "CURVE" and "CONVERT".
CURVE This program is indispensible where you need to develop accurate equations to represent graphical or numerical data. It can be used to fit equations to data by computing the A and B coefficients for polynomial, exponential, logarithmic and power equations, using the least squares method. The program can allow up to 25 data pairs. After a computation is computed, the program easily allows you to change to another equation to see if a better fit is possible. You can also add, subtract, or change any of the X and Y entries. The coefficient of determination is computed and displayed to determine the goodness of fit.
CONVERT Free download This program is extremely valuable for operations that need to convert complex Metric (SI) units to Engish units, and vise versa. Convert 200 entries in Metric/US units from Acceleration to Weight. Input any quantity of a known unit of measure, and output 13 Metric/SI/US equivalent units for ENERGY, 24 for VISCOSITY, 19 for PRESSURE, plus AREA, LENGTH, VOLUME, VELOCITY, TEMPERATURE, THERMAL CONDUCTIVITY, SPECIFIC HEAT, DENSITY, MASS, THERMAL DIFFUSIVITY, FORCE, TORQUE, WEIGHT, and more. Sheet metal and wire thickness equivalents for 8 different gauges in inch & millimeter units. Hardness number equivalents for 11 different scales, including tensile strength. Millivolt output vs. temperature for 9 types of thermocouples (B,E,J,K,R,S,T,W,W5). Weight of any size sheets, plates, circles, rings; round, square, octagon, hexagon & rectangular bars; round, square & rectangular tubing; for any material (18 metals are programmed); output in kg and lb.
In august 2000 we have decided to offer the convert.exe program free of charge. This program is currently 148kb and is available for download from the link provided. To get your copy click, download now.
