Rink is an open source unit-aware calculator. It can be used for physics and engineering calculations, as well as dimensionality analysis.
Rink supports most systems of measurements including SI, CGS, natural, international customary, US customary, UK customary, as well as historical measurements. In addition, Rink supports currency conversions.
Describes (hopefully) everything you need to know to use Rink's expression language.
The most common version of Rink is the command line interface rink.
| Package Manager | Command |
|---|---|
| Cargo | cargo install rink |
| Homebrew | brew install rink |
| Pacman | pacman -S rink |
| Nix | nix-env -i rink |
| Scoop | scoop install rink |
Downloads are also available at .
Rink is available via a web interface in addition to the terminal-based interface. Useful for doing calculations on mobile.
How much does it cost to run my computer each year? Say it uses 100 watts for 4 hours per day, and use the US average electricity cost.
> 0.1545$/kWh * 100W * (4 hours / day) to $/year
approx. 22.57196 USD / tropicalyear
If you made a solid sphere of gold the size of the moon, what would the surface gravity be?
> volume of moon * (19.283 g/cm^3) * G / (radius of moon)^2
approx. 9.365338 meter / second^2 (acceleration)
> ans to gravity
approx. 0.9549987 gravity (acceleration)
Ever heard someone joke about Americans measuring fuel efficiency as rods per hogshead? Let's try with the average US car fuel efficiency.
> 9.4 km/l to mpg
approx. 22.11017 mpg (fuel_efficiency)
> 9.4 km/l to rods per hogshead
approx. 445741.0 rod / ushogshead (fuel_efficiency)
And then you wonder, wait, what even are these units anyway?
> hogshead
Definition: ushogshead = 2 liquidbarrel = approx. 238480942.3 millimeter^3 (volume; m^3)
> liquidbarrel
Definition: liquidbarrel = 31.5 usgallon = approx. 119240471.1 millimeter^3 (volume; m^3)
> rod
Definition: rod = 5.5 yard = 5.0292 meter (length; m)
