Conversion Tables
Measuring pump performance factors can be muddled with varying units of measurement, so it is important that you have a guide for quickly and easily converting different units of measurement.
Below you will find a number of different pump conversion tables, including a flow rate conversion table, force conversion table and water conversion table. We hope these tables will be useful to you, and if you have any concerns or questions regarding conversions, please give us a call on 1800 439 607.
Please click on the type of conversion you require below (eg. Area, Volume, etc). The associated conversion table will then be displayed.
These conversion equivalents are based generally on A.S. 1376 – 1974. In some cases the degree of rounding has been adjusted.
