The quantities and units library for C++

A header only C++ library that provides type safety and user defined literals for physical units

A C++14-compatible physical units library with no dependencies and a single-file delivery option. Emphasis on safety, accessibility, performance, and developer experience.

A run-time C++ library for working with units of measurement and conversions between them and with string representations of units and measurements

linear algebra for tensors with symbolic and numeric scalars

a light-weight, header-only, dependency-free, C++14 library for ISO units

A comprehensive list of libraries used for converting, checking, and managing units of measurement and physical quantities

A type-safe representation of units with zero-run-time overhead. This library decouples the physical dimensions from the units themselves there by allowing to inter-convert between different systems such as SI and Imperial. The system allows for non-integer rational powers of physical dimensions as well(eg: L^2.5)

Go SDK for modeling physical units and conversion between them

WIP C++ physical units / dimensional analysis library. Focused on providing the cleanest possible errors.

DUQ is a python package for working with physical Dimensions, Units, and Quantities.

das2 stream utilities and catalog client in C

Python units, unit expressions, unit systems, united arrays.

std::chrono inspired physical quantity/unit representation and manipulation library for C++11/14/17

Getting the physical screen size in millimeters from the X window system using C++

Code base, projects, design decisions (tailored for *use* in your work and open for *dev*)

Simple C++ 14 units of measurement library for type safety when dealing with physical units calculations.

📦⚖️ Basic package to handle unit conversion. Comes also with mathematical operations, from-string parser and basic formulas to add relations between them.
