Introduction

In this tutorial we learn how to install udunits2 on Fedora 34.

What is `udunits2`

The Unidata units utility, udunits2, supports conversion of unit specifications between formatted and binary forms, arithmetic manipulation of unit specifications, and conversion of values between compatible scales of measurement. A unit is the amount by which a physical quantity is measured. For example Physical Quantity Possible Unit _________________ _____________ time weeks distance centimeters power watts This utility works interactively and has two modes. In one mode, both an input and output unit specification are given, causing the utility to print the conversion between them. In the other mode, only an input unit specification is given. This causes the utility to print the definition – in standard units – of the input unit. udunits2 2.2.28 3.fc34 x86_64 631 k udunits2-2.2.28-3.fc34.src.rpm updates A library for manipulating units of physical quantities http UCAR The Unidata units utility, udunits2, supports conversion of unit specifications between formatted and binary forms, arithmetic manipulation of unit specifications, and conversion of values between compatible scales of measurement.
