Physical quantities

Physical quantities are supported natively. The automatic dimensional analysis will help you discover mistakes.

Write quantities as: number unit. Use parentheses when ambigious.

Converting physical quantities

Calculating with quantities
// freefall time in vacuum sqrt(2*10 ft/1gee) // matrix operations with quantities A = [1kV/cm, 2kV/cm; 3m/s^2, 4m/s^2] A.() // area of a circle with a given radius (3cm)^2*pi // corner frequency of an RC filter 1/(2*pi * 100 Ohm * 33 nF) // battery life under a given load 1.2V * 900 mA*h / 100mW // period of a pendulum 2*pi*sqrt(20 cm/1gee) // range of a car 60 l * (26 mi/gal)
