Worked examples
2 x 1.000 / 0.45359237 = 4.4092 lb
0.75 x 0.910 / 0.45359237 = 1.5047 lb
10 x 0.45359237 / 0.840 = 5.3999 L
8.6 lb/gal = 1.0305 kg/L, so 3 x 1.0305 / 0.45359237 = 6.8156 lb
Which converter do you need?
You are in the right place when the question is "how many POUNDS does this many LITERS weigh?" Liters measure volume; pounds measure mass; density links them.
- Liter to kg converter - same math, but the answer comes out in kilograms (metric). Use it when you work in metric units.
- Kg to pounds converter - converts mass to mass (kg to lb). No density needed; use it when you already know the weight in kilograms.
- Kg to gallons converter - converts kilograms to US or imperial gallons via density. Use it when the volume must be expressed in gallons.
- A sibling tool covers fluid ounces to pounds for US fluid-ounce measurements.
Method and sources
- Definitions used: 1 lb = 0.45359237 kg exactly (international avoirdupois pound); 1 US gallon = 231 cubic inches = 3.785411784 L exactly; 1 US fl oz = 29.5735295625 mL exactly.
- Formulas:
pounds = liters x density (kg/L) / 0.45359237andliters = pounds x 0.45359237 / density (kg/L). - Densities are typical values near 20 C: water 1.000 (maximum at 4 C), sea water 1.025, whole milk 1.030, olive/vegetable oil 0.910, gasoline 0.737 (range 0.715-0.780), diesel 0.840 (ASTM D975: 0.830-0.855), kerosene 0.810, ethanol 0.789, acetone 0.785, honey 1.420 (range 1.38-1.45), maple syrup 1.370, glycerin 1.260, mercury 13.534.
- For trade, fuel, or laboratory use, measure the actual density of your batch - especially for gasoline, diesel, and honey, which vary.
Frequently asked questions
How do I convert liters to pounds?
Multiply the liters by the liquid's density in kg/L, then divide by 0.45359237. The formula is: pounds = liters x density (kg/L) / 0.45359237. For example, 2 liters of water: 2 x 1.000 / 0.45359237 = 4.4092 lb.
How many pounds is 1 liter of water?
1 liter of water weighs 2.2046 pounds. This uses water's maximum density of 1.000 kg/L at 4 C. At room temperature (20 C), water's density is about 0.998 kg/L, so 1 liter weighs 2.2002 lb.
How many pounds is 1 gallon of water?
1 US gallon of water weighs 8.3454 pounds (3.785411784 liters x 1.000 kg/L / 0.45359237). That is 128 US fl oz; 16 fl oz of water weighs 1.0432 lb, and exactly 1 lb of water is 15.3378 fl oz.
Why can't liters be converted to pounds directly?
Liters measure volume and pounds measure mass. They are connected by density: the same liter weighs 1.6248 lb as gasoline but 3.1306 lb as honey. Without knowing the substance's density, no correct answer exists, which is why this calculator asks for it.
How many pounds is 1 liter of honey?
1 liter of honey weighs 3.1306 pounds, using honey's typical density of 1.420 kg/L. Because honey's density varies with moisture content (about 1.38 to 1.45 kg/L), the true value can range from roughly 3.04 to 3.20 lb per liter.
How many pounds are in a liter of milk, olive oil, or gasoline?
1 liter of whole milk weighs 2.2708 lb (density 1.030 kg/L). 1 liter of olive oil weighs 2.0062 lb (0.910 kg/L). 1 liter of gasoline weighs 1.6248 lb (0.737 kg/L).
How do I convert pounds back to liters?
Divide instead of multiply: liters = pounds x 0.45359237 / density (kg/L). For example, 5 lb of water is 2.2680 liters, and 10 lb of honey is 3.1943 liters.
How many liters is 1 pound of water?
1 pound of water is 0.4536 liters, because 1 lb equals exactly 0.45359237 kg and water is 1.000 kg/L.
What should I do if I don't know the density?
Weigh a known volume: pour exactly 1 liter into a measuring jug, weigh it, and the weight in kilograms is the density in kg/L. As a starting point, water-like liquids (juice, milk) are close to 1.000 to 1.030 kg/L, and cooking oils are about 0.910 kg/L.
How do I enter a density given in lb/gal?
Multiply lb/gal by 0.119826427 to get kg/L. For example, 8.6 lb/gal x 0.119826427 = 1.0305 kg/L. As a check, water at 8.34 lb/gal converts to 0.9994 kg/L, essentially 1.000.
Is a liter of water always 2.2046 pounds?
Only at 4 C, where water is densest (1.000 kg/L exactly). At 20 C it is 2.2002 lb. The difference matters for precise work like fuel or chemical batching, but not for cooking.
What are the lightest and heaviest liquids per liter?
Of the substances in this calculator, gasoline is the lightest at 1.6248 lb per liter and mercury is the heaviest at 29.8374 lb per liter, almost 18 times heavier.
How many ounces is 1 liter of water?
1 liter of water weighs 35.2740 ounces (2.2046 lb x 16).
What is the difference between this tool and the liter to kg converter?
The liter to kg converter answers in kilograms (metric). This calculator answers in pounds and ounces (imperial/US customary). The math is identical: liters x density, then divided by 0.45359237 kg per pound.
Can I use this for cooking or fuel calculations?
Yes. For example, 0.75 liters of olive oil weighs 1.5047 lb, and 20 liters of gasoline weighs 32.4961 lb. For fuel and trade use, measure the actual density of your batch, since gasoline varies between about 0.715 and 0.780 kg/L with grade and temperature.
