Kg to gallons conversion calculator

The kilogram to gallons converter will save you time and help you convert a quantity from kg to gallons and vice versa.

All you need is to input the quantity for which you want to make the conversion. The calculator offers you a list of choices divided into various categories. Have a look through the categories in the What do you want to convert field and then select the correct item from the Item list. We have included a variety of substances, such as wet ingredients, like milk, oil, and ketchup, and even dry ingredients, like flour, salt, and sugar.

If you're going to convert from kg to gallons, just input the number of kilograms into the Weight field. And if you're going to convert from gallons to kg, do the same but with the number in gallons in the Volume field.

For example, if you want to estimate how much 7 kg of rice is in US gallons, follow these steps:

  1. Select cereals from the What do you want to convert? box.
  2. Select Rice from the Item list.
  3. Enter 7 into the Weight field.
  4. The result will be 2.57 gallons (US gallons).

Just to let you know, we have a gallons to pounds calculator as well if you are curious.

How to convert kg to gallons?

In the metric system, kilogram is the unit of weight, while in the imperial system, the unit of volume is gallons.

A gallon is equal to 4 quarts, 8 pints, or 16 cups.

Our kg to gallons calculator converts quantities both ways, i.e., from kg to gallons and from gallons to kg.

The ratio of a kilogram, kg, to a US gallon, gal, for water is:

1 kg = 0.26 gal

1 gal = 3.79 kg

This ratio is valid for water and quantities with a density equal to water, i.e., 1 g/ml. For UK gallon, the ratio is a little bit different:

1 kg = 0.22 gal

1 gal = 4.55 kg

You can convert any value you wish from kilograms to gallons, and vice versa - just follow the steps given below:

  • Kg to gallons

    To convert a quantity from kg to gallons, use the following, more detailed, formula:

    quantity in gallons = quantity in kg / (3.785412 × density)

where density is in g/ml. For example, you want to convert 9.5 kg of cooking oil to gallons, the vital thing to know is the density of oil is 0.88 g/ml. If you place it in the formula along with 9.5 kg, your result is 2.85 gallons.

  • Gallons to kg

You can use the formula to convert any quantity from kilograms to gallons as long as you know its density in g/ml. This conversion is from a unit of volume to weight, and so density is crucial to solving it:

quantity in kg = quantity in gallons * 3.785412 × density

Convert kg to gallons of water

A conversion between kilograms and gallons is actually a conversion between weight and volume. Since the density of water changes depending on its temperature and purity, the amount of space that 1 kg of water occupies will vary with these factors. So, for example, for pure water at 4 °C, the conversion is:

  1. 1 kg = 0.26 gal of water
  2. 1 gal = 3.79 kg of water

The thing is with this kind of conversion - we rarely think about it! However, you may find such a calculation useful in your everyday life, even if it is just to satisfy your curiosity. If you're standing in the supermarket, with your grocery list in hand, you may wonder how many kg are in a gallon of water, or how many kilograms are in a gallon of ketchup?

FAQ

How many gallons are there in 24 kg of olive oil?

There are 6.91 gallons in 24 kg of olive oil, as the density of olive oil is 0.918 g/ml. The density of the ingredient is crucial for the conversion from a unit of weight to volume.

To convert a quantity from kg to gallons, you may use the formula:

quantity in gallons = quantity in kg / ( 3.785412 × density)

How many kilograms are there in 2.6 gallons of ketchup?

There is 11.32 kg in 2.6 gallons of ketchup. To find it:

  1. Multiply your desired quantity of 2.6 gallons by 3.785412.

  2. Check the density of ketchup, which is approximately 1.15 g/ml.

  3. Multiply the results from the above steps to find the weight in kilograms.

  4. The following formula summarizes all steps:

    quantity in kg = quantity in gallons × 3.785412 × density

Are kilogram and gallon the same unit?

No, kilograms and gallons are not the same units. Kilogram is a unit of weight and gallons is a unit of volume. You can convert these units into each other if you know the density of a substance. To convert a quantity from gallons to kg, you may use the formula:

quantity in kilogram = quantity in gallons × 3.785412 × density

where density is in g/ml. And to convert kg to gallons, the formula is shuffled, which looks like this:

quantity in gallons = quantity in kg / (3.785412 × density)

What is the ratio between kilograms and gallons?

The ratio of kilograms to gallons is 1:0.26417 or 3.7854:1. It is valid for any ingredient with a density equal to that of water, i.e., 1 g/ml.

Kg, or kilogram, is a unit of weight and a gallon is a unit of volume. So, from this, you may understand that the conversion between kilograms and gallons is a conversion of weight to volume, and knowing the density is necessary for the calculation.

Can I convert 26 kg of water to gallons?

Yes, you can. 26 kg of water is equal to 6.868 gallons. To convert a quantity of water from kg to gallons, you may use the formula:

quantity in gallons = quantity in kg × 0.26417

or

quantity in gallons = quantity in kg / 3.7854

Remember, this formula applies to quantities with a density equal to water, i.e., 1 g/ml.
