ToolBox

ToolBox is an extended unit converter. ToolBox converts, besides the usual units, sexagesimal angles, solid angles, number systems, units of radioactivity, consumption, concentration and cable dimensions. Furthermore, ToolBox calculates spherical surface areas and voltage drop in electrical wires. Setting values for the axle geometry of cars can also be calculated or converted with it.

Geo-1

Calculation of geological parameters (width of outcrop, true and apparent thickness, true and apparent dip) by means of various geological factors.

Version: 1.2 (03/2020)

RockClass

RockClass is used to calculate the CIPW standard from geochemical analyzes of igneous rocks and allows rock classification using the Streckeisen (QAPF) and TAS (total alkali vs. silica) diagrams. The results of the calculations and the diagrams can be easily downloaded as csv and png files.

Version: 1.4 (01/2023)
Major changes to the user interface; fixed an Ilmenite / Sphene allocation bug; New function: Streckeisen diagrams can now be created directly without having to calculate the CIPW standard
