Liters to Pounds Calculator
Volume and weight are not the same thing — a litre of honey weighs almost twice as much as a litre of gasoline. Select your liquid (or enter a custom density) and get the weight in pounds, kilograms, ounces, and grams instantly.

How does this calculator work?
Pounds = litres × density (kg/L) × 2.20462. Water: 1 L ≈ 2.205 lb. Milk: ≈ 2.271 lb. Gasoline: ≈ 1.624 lb. Honey: ≈ 3.130 lb. Density varies with temperature and composition — use the custom option for precision work.
Formula
How this is calculated
To convert a volume in litres to a weight in pounds, you need two pieces of information: the volume and the density of the liquid. Density (ρ) is the mass per unit volume, expressed here in kilograms per litre (kg/L), which is numerically identical to grams per millilitre (g/mL) and tonnes per cubic metre (t/m³). The mass in kilograms is simply volume × density (m = V × ρ), and the mass in pounds follows from the exact conversion 1 kg = 2.20462 lb.
The density values used here are typical at room temperature (~20 °C) and standard atmospheric pressure. Water is 1.000 kg/L at 4 °C and approximately 0.998 kg/L at 20 °C — the difference is negligible for most purposes. Fuels, oils, and beverages vary by blend and temperature; the values provided are representative central estimates and may differ slightly from your specific product. For precision applications, use the "Custom density" option and enter the value from a material data sheet.
Density decreases slightly as temperature rises (liquids expand when heated). If accuracy matters, adjust the custom density for your operating temperature using the product's technical data sheet.
Frequently asked questions
A litre of water weighs approximately 2.20462 pounds (1 kg) at 4 °C. At room temperature (20 °C) it is about 2.202 lb — a negligible difference for everyday purposes.
Because the conversion depends on the density of the liquid. 1 litre of water weighs 2.20 lb, but 1 litre of honey weighs about 3.13 lb, and 1 litre of gasoline only about 1.62 lb. There is no single fixed factor — you always need the density.
The preset values are standard engineering reference densities at approximately 15–20 °C and 1 atm. Real products can vary with temperature, blend, and composition. For accurate results in technical or commercial contexts, use the "Custom density" option with the value from the liquid's safety data sheet (SDS) or specification.
