How the mL → lbs conversion works
We first convert your density to the SI base kg/m³, convert volume from mL to m³, multiply to get mass in kilograms, and finally convert kilograms to pounds (1 kg = 2.20462262185 lb). The calculator updates instantly as you type—no buttons required.
The formula for mL to lbs conversion
lb = mL × ρ(g/mL) × 0.00220462262. If your density is in kg/m³ use lb = (mL / 1,000,000) × ρ(kg/m³) × 2.20462262.
The formula for pounds to mL conversion
mL = lb ÷ ρ(g/mL) ÷ 0.00220462262. Or with SI density: mL = (lb × 0.45359237 / ρ(kg/m³)) × 1,000,000.
Expressing density in lb/mL units
To convert a density from g/mL to lb/mL multiply by 0.00220462262. Example: water 1 g/mL ≡ 0.00220462262 lb/mL. You can also use lb/gal (US/UK) or lb/ft³—pick whatever source unit you have; the tool normalizes it automatically.

How many mL are in an lb?
It depends on density: mL per lb = 453.59237 ÷ ρ(g/mL). Water (ρ≈1 g/mL) → 453.592 mL; honey (ρ≈1.42 g/mL) → ~319 mL.
How many mL are in a pound of water?
About 453.592 mL at room temperature, since water density is ≈1 g/mL.
Behind the scenes
The app converts density units losslessly using double precision, rounds only for display (you control “Precision”), and guards against invalid inputs.
