- Canada’s sprayer world mixes Metric and US Imperial, causing confusing calibration questions and painful unit conversions.
- This new Sprayer Calibration and Unit Conversion Tool converts many agriculturally relevant units and simplifies common calibration tasks.

Canada, like most of the world, is officially Metric. America operates using the US Imperial system. It sounds very cut and dried, doesn’t it?
However, anyone that’s tried to calibrate a sprayer in Canada quickly discovers that we’re really an amalgam of the two systems. We like to call it “Mock-tric“. By way of evidence, some operators still adhere to the dreaded L/ac. You know who you are. To be fair, some of our sprayers and nozzles originate from the states, meaning nozzle tables and rarely, sprayer indicators, can be in US Imperial.
This leads to mind-bending questions such as:
I drive 12 mph, spraying 150 L/ha and my pressure is about 40 psi. How many ml/min should my 72 nozzles emit for a product that wants a 6 oz/acre acid equivalent?
Cue the quiet sobbing…
Frustrated back in 2017, we created a set of conversion tables to help operators with almost any Imperial/Metric emergency. Admittedly, they were in 4-point font and therefore too cumbersome for practical use. We’ll keep one here for posterity.
Happily time has marched on and we now have a better way. Explore our new Sprayer Calibration and Unit Conversion Tool, below. While it doesn’t do it all, it certainly does a lot! You can:
- Convert between common (and some uncommon) agriculturally-relevant units.
- Calibrate a field sprayer for both broad acre or banded applications.
- Calibrate an airblast sprayer for almost every traffic pattern and swath width.
- Calibrate a plot sprayer, either for a handheld boom (any number of nozzles) or for a backpack sprayer mist/wand in 3D rows.
- Calibrate a fogger for common closed environment structures
To use this suite of calculators correctly, the user needs some agronomic understanding of what these variables mean and how to obtain them. In order to provide context, and reduce the friction, we’ve added a link to relevant articles at the top of each calculator. We’ve tried to validate every path, but if you find a bug, please let us know.
