Duct Calculator

The S&P duct calculator allows three different calculations to be carried out quickly and with ease. These calculations are divided in four areas:
1. Diameter converter, which allows converting circular to equivalent rectangular ducts.

2. Calculator of different ventilation parameters, with which will be able to obtain the diameter, the air speed, the airflow and the dynamic pressure of your installation.

3. Pressure drop calculation tool for installations with straight sections and duct system elements.

4. Units converter, with which you will be able to transform speed, airflow, power and pressure units for other equivalents in different scales.

S&P (Soler y Palau) is an international Spanish company. Spain from Europe, and sorry, we don't use imperial we use metric. Sorry about that. Works fine, it helps a lot.

in America we usually do not measure in meters..app is useless unless converts to imperial measurement..had to look for English translation. then could not convert.

362 countries use the metric system, and 1 (one) put men on the moon.

Stop complaining about inferior unit systems

This ductulator doesn't use the imperial measuring system, it uses metric. Useless to me.

Like the general layout and feel of the interface. Lots of separate functionality that could be useful, such as conversion of imperial to metric units or conversion of circular duct to square duct. Severe limitations in the actual basic duct sizing functionality. Input units are limited. Only m3/s. Can't see all parameters on one screen e.g. duct dia, air speed, flow rate and pressure drop Needs ability to switch units on input screen.

Metric with no conversion.
