unit-conversion

A command-line tool for converting physical quantities between the CGS (Centimetre-Gram-Second) and SI (International System of Units) unit systems.

Supported quantities

Quantity	CGS unit	SI unit
Length	cm	m
Mass	g	kg
Time	s	s
Force	dyn	N
Energy/Work	Erg	J
Power	Erg/s	W
Pressure	dyn/cm²	Pa

Requirements

• C++23 compiler (GCC 13+ or Clang 17+)
• CMake 3.20+

Build

Use the provided script (tho it may not work for everyone):

# Full rebuild + run
bash run.bash root

# Run only (assumes build already exists)
bash run.bash

Usage

The program runs interactively in a loop:

1. Select conversion direction: CGS -> SI or SI -> CGS
2. Select the quantity to convert
3. Enter a positive numeric value
4. Repeat or exit

Select what type of conversion:
1. CGS -> SI
2. SI -> CGS
Enter a value (1-2): 1

Select what do you want to convert:
1. Length (cm -> m)
...
Enter a value (1-7): 1

Enter a value: 150
Converted value: 1.50 m

Would you like to convert another value ? (y/n):
