Hose End Sprayer Conversion Chart: Full Discussion
A hose-end sprayer is a tool that connects to the garden hose and siphons liquid products from a bottle.
Products like Weed B Gon or Roundup are mixed with water through the hose-end sprayer. They create a solution that can be sprayed onto plants or surfaces. Self-mixing hose end sprayers and manual hose end sprayers both are available in the market.
The conversion chart of the hose-end sprayer provides a guide for determining the correct amount of liquid product to mix with water.
This conversion rate is based on the desired concentration or application rate. For specific products, there are different dilution ratios or measurements.
Here’s a conversion chart made of popular hose-end sprayer brands like Ortho Dial N Spray, Chameleon, Chapin, etc.
This is to give you an idea of the minimum amount of product you will require for each dial setting:
| Garden | Lawn | |
| Dial | Ounces/1000 sq ft | Ounces/ Gal |
| 1 TSP | 0.5 | 0.16 |
| 2 TSP | 1.0 | 0.33 |
| 4 TSP | 2.0 | 0.49 |
| 1 OZ | 3.0 | 1 |
| 2 OZ | 6.0 | 1.99 |
| 3 OZ | 8.8 | 3 |
| 4 OZ | 11.5 | 4 |
| 5 ⅓ OZ | 15.3 | 5.22 |
| 6 OZ | 17.3 | 6 |
| 8 OZ | 23.0 | 8 |
This number is the minimum amount you need for each dial setting mentioned here. The amount needed for each product in different hose end sprayers will vary slightly.
This difference is due to the design difference of the nozzle and the variance in dial settings. You’ll find a brand’s hose-end sprayer mix ratio in the product’s manual. You can visit the product’s website for this as well.
But to use the conversion chart you need to understand the measurements like the hose end sprayer 5 to 1 ratio.
So to understand these measurements better let’s take a look at this Ortho Dial N Spray hose end sprayer chart. We’ll explain what each column and row represents:
- In this conversion chart, the ‘Dial’ column indicates the dial setting on the hose end sprayer for each Level. There are 14 dial settings in this hose-end sprayer, from 1 TSP up to 8 OZ.
- The “Ounces/Gal” column under ‘Garden’ represents the amount of liquid substance(in ounces) you need to add per gallon of water for that level’s dial setting.
- The “Ounces / 1000 sq. ft” column indicates the number of liquid substances you need to add for every 1000 square feet of lawn for that corresponding level’s dial setting.
If you are treating a level 1 lawn for example, you need to set the dial on the hose end sprayer to 1 TSP and add 0.167 ounces of a liquid substance to one gallon of water. And for 1000 square feet of lawn it would be 0.5 ounces of liquid substance.
The self-mixing hose end sprayers do this mixing automatically. So if you Turn your dial to 5 or 5 ⅓ it will automatically add 5.33 ounces of liquid with 1 Gallon of water.

Why is it Important to Maintain the Accuracy of the Chart?
No matter which conversion chart you use, you need to follow it accurately for proper application of the product. Otherwise, it may lead to these problems:
Under-dilution
If you are using less amount of product than necessary, your spraying the lawn or garden will be completely ineffective. As the plants won’t have adequate pest control or sufficient nutrients for growth.
Over-dilution
Using too much or over-dilution on the other hand, runs the risk of potentially harming the plants or lawn surface. The plants could be even severely burned due to excessive concentration. A lot of substance will be wasted as well.
Inconsistent Results
If the Dial setting is not correct for a certain amount of liquid it can easily result in uneven coverage or ineffective treatment.
For example, if your dial is set to 4 TSP which indicates the Level 5 row in the chart. So, you should mix 0.66 ounces of liquid substances for every gallon.
You will notice that the result from that application is not consistent or satisfactory. Moreover, the wrong dilution ratio can damage your plants completely.
This is why you need to carefully read and follow the instructions provided by the product manufacturer. Later on, check the hose end sprayer conversion chart for accurate measurements.
Tips for Accurate Application of Hose End Sprayer
Even if you properly use the conversion chart, it will all be in vain if the hose end sprayer is not applied properly. You will end up with a sprayer not working at all.

- Follow the instructions provided by the sprayer manufacturer to calibrate your specific sprayer model. Calibration is important to ensure accurate dilution rates and application rates.
- Spray the designated plants or surfaces with plain water to check whether they will cover the targeted area or not.
- Read and follow the instructions provided by the product manufacturer regarding the dilution ratio and application rates.
- Maintain the same pressure and nozzle setting throughout the application. Try to move the sprayer in a controlled manner as well.
- Wear protective gear like gloves and goggles while mixing the solution and spraying to avoid any contact with the product.
FAQs
Why Calibration is So Important for Hose End Sprayers?

What is the Flow Rate of A Garden Hose?
The flow rate of a garden hose is usually between 9 to 17 GPM (gallons per minute). The average rate is 12-13 GPM. This rate can vary depending on the diameter and length of the hose, water pressure level, and other factors.
End Words
That’s the end of our discussion on hose end sprayer conversion charts. It’s really important to stick to the conversion chart measurements to ensure the proper application of the product.
Improper calculation can easily lead to an over or under-dilution rate, which can do more harm than improvement. Always double-check to avoid such a case and wear protective goggles and gloves to any contact with the product
