Measurement Unit Conversion Tool
To allow for an accurate dosing of your swimming pool, hot tub or spa chemical products, you should first make sure all the measurements you are working with are in the same units as those provided in the instructions.
If you need to calculate the volume of water in your swimming pool to get started, you can visit our Water Volume Calculation page, which tells you how to do this.
You may have some of your volume measurements in Cubic Metres, Litres, UK or even US Gallons depending on where you got your information from. Whether your dosing rates need to be in Metric or Imperial units, here’s a guide on how to convert volume measurements:
