KG To Liters

KG to Liters Soil

Convert kilograms of topsoil, potting mix, clay, compost or peat moss to liters. Garden products are often sold by volume, so this shows how many liters a bag weight gives.

How KG to Liters Soil Works?

KG to Liters Soil works by dividing the mass of soil in kilograms (kg) by the bulk density of soil in kilograms per liter (kg/L). The converter holds 5 materials from 0.150 kg/L (peat moss) to 1.750 kg/L (clay (moist)), and the default is topsoil (loose) at 1.220 kg/L. The volume updates in real time as the weight changes.

Mass20 kg
÷ Bulk density1.220 kg/L
Volume16.39 L
20 kg of topsoil (loose) ÷ 1.220 kg/L = 16.39 L (4.33 US gallons, 3.61 UK gallons).

4 steps to convert soil from kg to liters

  1. Choose the direction: "kg → Liters" for mass to volume or "Liters → kg" for volume to mass.
  2. Select 1 of 5 materials: topsoil (loose), potting mix, clay (moist), compost and peat moss.
  3. Enter the weight in 1 of 7 mass units: kilograms (kg), grams (g), pounds (lb), ounces (oz), stone (st), tonnes (t) or milligrams (mg).
  4. Read the volume in 1 of 13 volume units, including liters (L), milliliters (mL), US gallons (gal), UK gallons, US cups, cubic meters (m³) and oil barrels (bbl).

The converter changes the input to kilograms, divides the kilograms by the bulk density and changes the liters to the selected output unit. The live container fills to the result, and the container row counts 10 L buckets, 85 L wheelbarrows and 1 m³ bulk bags.

KG to Liters Soil Formula

The KG to Liters Soil formula is liters = kilograms ÷ 1.220, written as V = m ÷ ρ with ρ = 1.220 kg/L for topsoil (loose). The formula has 3 variables:

  • V (volume) is the result in liters (L).
  • m (mass) is the weight of soil in kilograms (kg).
  • ρ (rho, bulk density) is the mass of soil per unit volume in kilograms per liter (kg/L).
m ρ V
VolumeV = m ÷ 1.220
Massm = V × 1.220
Bulk densityρ = m ÷ V

3 worked examples of the KG to Liters Soil formula

  1. 1 kg ÷ 1.220 kg/L = 0.82 L (0.22 US gal).
  2. 20 kg ÷ 1.220 kg/L = 16.393 L (4.33 US gal).
  3. 100 kg ÷ 1.220 kg/L = 81.967 L (21.65 US gal).

The reverse formula is kilograms = liters × 1.220: 1 L of topsoil (loose) weighs 1.220 kg (1,220 g, 2.69 lb), and 1 US gallon weighs 4.62 kg (10.18 lb).

Bulk density of soil

Bulk density includes the air between grains or particles, so soil weighs less per liter than the solid material. Tapping, packing or moisture raises the bulk density of soil by 10–20%, and 1 kg of packed soil fills 80–90% of the poured volume.

KG to Liters Soil Conversion Table

The KG to Liters Soil conversion table lists the volume of topsoil (loose) in liters (L), US gallons and UK gallons for 12 masses from 0.5 kg to 1,000 kg at 1.220 kg/L. A second table lists 1, 5, 10, 25 and 50 kg for all 5 materials.

Liters in 1 kg of 7 substances. Bars longer than water mark substances lighter than water.

1 liter equals 1,000 milliliters (mL), 0.264 US gallons, 0.220 UK gallons and 33.8 US fluid ounces (fl oz), so each value in the table converts to these units by multiplication.

What Is KG to Liters Soil?

KG to Liters Soil is a mass-to-volume conversion that turns the mass of soil in kilograms (kg) into the volume in liters (L), using the bulk density of soil as the conversion factor.

Soil is a mix of minerals, organic matter, water and air. Topsoil has a bulk density of 1.22 kg/L, clay soil 1.75 kg/L, potting mix 0.45 kg/L, compost 0.55 kg/L and peat moss 0.15 kg/L.

  • 1 kg of topsoil (loose) fills 0.820 L (820 mL, 27.7 US fl oz).
  • 1 L of topsoil (loose) weighs 1.220 kg (1,220 g, 2.69 lb).
  • Topsoil (loose) is 22% denser than water, so 1 kg of topsoil (loose) fills 0.180 L less than 1 kg of water.
Topsoil (loose)0.82 L
Water1.00 L
Dry Sand0.63 L
Potting Mix2.22 L
1 kg of 4 substances fills 4 different volumes.

The International Bureau of Weights and Measures (BIPM) defines the kilogram (kg) as the SI base unit of mass, and the liter (L) equals 1 cubic decimeter (dm³), a unit accepted for use with the International System of Units (SI).

What Are the Uses of KG to Liters Soil?

There are 4 main uses of KG to Liters Soil: potting, raised bed filling, bulk delivery and landscaping.

  • Potting: Potting mix bags list liters: a 20 kg bag of topsoil fills 16.4 L, and 20 kg of potting mix fills 44.4 L.
  • Raised bed filling: A 1 m × 2 m × 0.3 m bed holds 600 L, or 732 kg of topsoil.
  • Bulk delivery: Topsoil sells per tonne and per cubic meter: 1 t fills 0.82 m³.
  • Landscaping: Landscapers convert wheelbarrows (85 L) to kilograms: 85 L of topsoil weighs 104 kg.

KG to Liters Soil returns estimates from typical bulk density values. Weigh 1 L of the product or read the product data sheet, if the job needs an exact figure.

Frequently Asked Questions

How many liters is 1 kg of soil?

About 0.82 L, using a typical bulk density of 1.220 kg/L for topsoil (loose).

How much does 1 liter of soil weigh?

About 1.220 kg (1220 g).

How many liters is a 20 kg bag of potting mix?

A 20 kg bag of potting mix holds 44.44 L at a bulk density of 0.450 kg/L.

How many liters is 1 kg of compost?

1 kg of compost is 1.818 L at a bulk density of 0.550 kg/L. Moist or compacted compost holds less volume per kilogram.

Why not just use 1 kg = 1 liter?

That rule only works for water. Dry goods trap air between grains, so their liters per kilogram depend on the material and how it is packed.
