# kwh-calc
|
|
|
|
Calculate cost of electricity.
|
|
|
|
## How to use
|
|
|
|
```shell
|
|
$ kwh-calc [OPTIONS] price wattage interval [interval ..]
|
|
```
|
|
|
|
Options are -v, --version to show program's version; and -h, --help to show usage of a program.
|
|
|
|
`price` is a price per KWh. `wattage` is how many Watts being consumed. `interval` is for how long.
|
|
|
|
`interval` is in seconds, but you can specify a unit. Units are the following:
|
|
`m` for minutes; `h` for hours; and `d` for days. There could be as many `interval`s passed as you need.
|
|
|
|
Here is an example:
|
|
|
|
```shell
|
|
$ kwh-calc 3.68 120 30d 2h
|
|
```
|
|
|
|
P.S.: Yeah, I pay 3.68 rubles per KWh. Which is just $0.05. :)

|
## Installation
|
|
|
|
### Manually
|
|
|
|
First run `make` to build a program, and then `make install` to copy executable in `/usr/bin/`. Later, use `make uninstall` to delete it, or just delete `/usr/bin/kwh-calc`.
|
|
|
|
### For ArchLinux

You can take a [PKGBUILD](/Arav/kwh-calc/raw/branch/master/PKGBUILD) file and in a directory with it run `makepkg -i`. |
