A simple distance (metric or SI unit), energy, and temperature unit converted through C++ coding language.
Each unit conversion is separated into separate files:
Energy: nrg.cpp and nrg.h
Distance: SI-conv.cpp and SI-conv.h
Temperature: temp.cpp and temp.h
The main file that executes the code is labelled conversions.cpp and the input-output files are named io.cpp and io.h.
