The tool is a physic formula for Engineering or Science : Python 3.6+.
- Area Formula
- Volume Formula
- Electric Formula
- Pressure Formula
- Temperature Formula
- First : Check python version and PIP version

- Second : Install lib engineering-tool

- Third : Test lib in python shell

from engineering_tool.electrics import Power
voltage = 15 # Volt
current = 2.5 # Amp
power = Power.VoltageAndCurrent(voltage,current)
print("Power is %.2f Watt"%power)The Engineering tool documentation is the best place to start.after that try opening an issue.
