This hydrogen peroxide dilution calculator will occupational for diluting any type of concentration the hydrogen peroxide. A most the charts you’ll find online are only for diluting 35% peroxide down to 3%. The didn’t seem an extremely useful due to the fact that a lot of of civilization are trying to transform different concentrations, such as 28% and 31%.

You are watching: How to dilute hydrogen peroxide 6 to 3

Use the calculator to dilute from any type of concentration, down to any concentration, and also in any quantity.

Warning: Hydrogen peroxide in concentrations over 6% is caustic and can result in injury if it comes into contact with skin or eyes. Also, nothing swallow it….That would certainly be bad.

How to the usage Calculator

Initial H2O2 Concentration: get in the starting concentration here. Example: 35Desired Dilution To: go into the wanted final dilution. Example: 3Total Diluted Volume: get in the desired total volume. Example: 3.8

There is no calculate button, the calculations will be performed immediately as you enter values.

Initial H2O2 Concentration common “Food-Grade” hydrogen peroxide concentration range from 28-35%.
Desired Dilution To for hydroponic gardering, the most usual dilution is 3%.
Total Diluted Volume get in the total volume (in Liters) that diluted H2O2 you want to produce.Example: for 1 Gallon, enter 3.8

35% Food great Hydrogen Peroxide 1 Gallon
I obtain emails all the time asking where to to buy 35% hydrogen peroxide. This is where I gain it. It"s terrific for hydroponic applications.

What i like:

Zero stabilizers - Zero additives - quick shipping
Buy from BulkPeroxide
This is a sponsored attach for a product I actively use and also happily recommend.

Common Volume Conversions

These conversions make it a much easier to convert metric to U.S. Traditional volume. The values room close approximations.

1 gal = 3.8 L1/2 festival = 1.9 L1 Qt = .96 L1/2 Qt = .48 L
1 Pt = .48 L1/2 Pt = .24 L
Gal = Gallon | Qt = Quart | Pt = Pint | together = Liter

Why Metric Measurements?

Being from the United claims of America, I completely get the preference for pints, quarts, gallons, etc. The trouble with these dimensions rears that is head once you begin breaking out the 1/4 cup, 1/2 cup, 3/4 cup, cup, tablespoon, teaspoon, and half teaspoon measurements. I"m no a pan of having a drawer complete of measuring cups.


Premium measuring Cylinder collection - 25ml, 50ml, & 100ml

I usage this i graduated cylinder set all the time for tiny measurements. They"re well-marked and also work great for diluting hydrogen peroxide and mixing nutrient solutions.

Using metric volume makes dilution measurement really easy.

Example: 35% H2O2 diluted to 1 pint that 3% H2O2

(2 TBSP + 1TSP 35% H2O2)+(1 3/4 cup + 4 TSP Water) = 1 Pint 3% H2O2OR(41ml 35% H2O2) + (439ml Water) = 480ml 3% H2O2 (approx. 1 Pint)

The simplicity of making use of metric measurements is why I made decision to go that path with this calculator. Big box stores offer mixing cup (usually close to the paint section) that have actually milliliter and liter markings. Personally, ns buy 1 quart cups, 1 liter, and also 3 liter buckets and have discovered them to it is in extremely useful for diluting liquids.

Common uses of H2O2 in Hydroponics

Hydrogen peroxide is an reliable tool for gardeners, particularly hydroponic gardeners. Some of the most common uses in hydroponic gardening are:

Treating "Root Rot" on influenced plantsKilling bacteria & fungal expansion in hydroponic systemsAs a nutrient additive to boost oxygenation & nutrient uptake, and also as a food-safe bactericide & fungicide.Cleaning & sterilizing hydroponic equipment, tools, and also components in between growing cycles.As a diluted floor amendment because that soil-based gardens & plants

When used as a nutrient additive in hydroponic systems, 30-45ml 3% H2O2 every gallon of nutrient solution should administer benefits without posing any risk come the plants. Always begin with a short dose and also increase slowly to ensure plant health.

Household Cleaning

Did you know that hydrogen peroxide is more effective 보다 chlorine bleach in ~ sanitizing and sterilizing porous surfaces?

Peroxide deserve to be used as a household cleaner and sterilizer. Be mindful using concentrations over 6% as it can damage surfaces. Hydrogen peroxide have the right to oxidize metals, so store that in mind as you clean.

Of course, if she wanting to make new metal watch rusted and also aged, hydrogen peroxide is the rapid ticket come instantly-aged spring DIY projects.

Happy Diluting!

I hope you find this calculator beneficial for diluting hydrogen peroxide. It’s one of the devices on this website that i return to generally for my own use. If you like it, you re welcome share it!
