How many milliliter are in a pound?

Quick Answer

There are 454 grams in 1 pound. Since 1 milliliter of water equals 1 gram, there are 454 milliliters in 1 pound.


To determine how many milliliters are in a pound, we first need to understand the relationship between pounds, grams, and milliliters.

Pounds to Grams

A pound is a unit of measurement used in both the imperial and United States customary systems to measure mass. One pound is equal to 16 ounces or 453.592 grams. For simplicity’s sake, we’ll round this to 454 grams per pound.

So 1 lb = 454 g

Grams to Milliliters

The gram is the SI unit for measuring mass in the metric system. A milliliter is a unit of volume in the metric system that is equal to 1 cubic centimeter.

For water at 4° Celsius, 1 milliliter is equivalent to 1 gram. This allows us to easily convert between grams and milliliters for water.

So 1 g = 1 mL

Pounds to Milliliters

By combining the relationships above, we can determine that:

1 lb = 454 g
454 g = 454 mL

Therefore, 1 lb = 454 mL

There are 454 milliliters in 1 pound.

Showing the Math

We can also show the calculation step-by-step:

1 lb = 454 g
1 g = 1 mL
454 g x (1 mL/1 g) = 454 mL

So cross-multiplying the units, we end up with 454 milliliters in 1 pound.


Let’s look at some examples to demonstrate how to convert pounds to milliliters:

1 Pound

1 lb x (454 mL/1 lb) = 454 mL

There are 454 mL in 1 lb.

2 Pounds

2 lb x (454 mL/1 lb) = 908 mL

There are 908 mL in 2 lb.

0.5 Pounds

0.5 lb x (454 mL/1 lb) = 227 mL

There are 227 mL in 0.5 lb (or half a pound).

3.25 Pounds

3.25 lb x (454 mL/1 lb) = 1476 mL

There are 1476 mL in 3.25 lb.

Milliliters to Pounds Conversion Table

To make converting between pounds and milliliters even easier, refer to this handy conversion table:

Pounds Milliliters
0.5 lb 227 mL
1 lb 454 mL
2 lb 908 mL
3 lb 1362 mL
4 lb 1816 mL
5 lb 2270 mL
10 lb 4540 mL

To use the table, simply locate the pound amount you want to convert and find the corresponding number of milliliters.

Converting Milliliters to Pounds

We can also use the relationship between pounds and milliliters to convert in the opposite direction, from milliliters to pounds.

The conversion equation is:

Pounds = Milliliters / 454

So to convert milliliters to pounds, simply divide the milliliter amount by 454.

For example:

908 mL / 454 mL/lb = 2 lb

1362 mL / 454 mL/lb = 3 lb

Milliliters to Pounds Examples

Let’s look at some examples converting milliliters to pounds:

454 mL

454 mL / 454 mL/lb = 1 lb

454 mL is equal to 1 lb.

200 mL

200 mL / 454 mL/lb = 0.44 lb

200 mL is equal to 0.44 lb.

1816 mL

1816 mL / 454 mL/lb = 4 lb

1816 mL equals 4 lb.

1000 mL

1000 mL / 454 mL/lb = 2.2 lb

1000 mL is approximately equal to 2.2 lb.

Comparing Pounds and Milliliters of Other Substances

It’s important to note that the conversions discussed so far apply specifically to water at 4°C.

If we are measuring the volume of other liquids or substances, the equivalencies may differ since they will have different densities.

For example:

Vegetable Oil

1 lb of vegetable oil = 508 mL

Vegetable oil is less dense than water, so there are more milliliters in a pound.


1 lb of honey = 363 mL

Honey is denser than water, so there are fewer milliliters in a pound of honey.

Granulated Sugar

1 lb of granulated sugar = 201 mL

Granulated sugar is denser than both honey and water. 1 pound contains only 201 mL.

So while 454 mL = 1 lb is a handy rule of thumb, it’s important to consider the substance being measured if true precision is needed. Checking a substance’s density can provide the exact conversion.

Typical Uses

Some common uses and situations where people convert between pounds and milliliters include:

– Cooking recipes – To convert the units used in a recipe, for example converting milliliters of liquid ingredients to pounds when scaling up a recipe.

– Food labeling – Converting between milliliters and pounds when calculating nutrition information to label food products.

– Chemistry experiments – Chemists may need to convert between mass in pounds and volume in milliliters when preparing solutions.

– Pharmacology – Medical professionals may convert doses from pounds to milliliters or vice versa when calculating medication dosages.

– Industrial applications – Engineers may need to convert between pounds and milliliter volumes for inventory, shipping, or production.

– Everyday use – Conversion may be useful for common situations like estimating shipping costs based on weight.


There are 454 milliliters (mL) in 1 pound (lb) of water at 4° Celsius. This equivalency can be used to easily convert between pounds and milliliters by multiplying or dividing by 454. While not exact for all substances, it provides a good approximation and rule of thumb. Knowing how to convert units comes in handy for cooking, chemistry, medicine, manufacturing, and many everyday situations.
