Ml to Kg

Liquid Density Metrology & BIPM Standards

The relationship between volume (mL) and mass (kg) is determined by mass density (ρ):

Mass (kg) = Volume (mL) × ρ1,000

Primary Liquid Density Benchmarks

• Automotive Gasoline: 1,000 mL = 0.740 kg = 1.63 lbs

• Ethanol Alcohol: 1,000 mL = 0.789 kg = 1.74 lbs

• Diesel Fuel: 1,000 mL = 0.832 kg = 1.83 lbs

• Olive Oil: 1,000 mL = 0.918 kg = 2.02 lbs

• Pure Water @ 4°C: 1,000 mL 1.000 kg = 2.205 lbs

• Whole Milk: 1,000 mL = 1.030 kg = 2.27 lbs

• Glycerin: 1,000 mL = 1.261 kg = 2.78 lbs

• Pure Honey: 1,000 mL = 1.420 kg = 3.13 lbs

• Liquid Mercury: 1,000 mL = 13.534 kg = 29.84 lbs

How to Use This Calculator

Enter your Volume / Mass Value to Convert (e.g. 1000.0), Fluid Substance & Specific Density — choose from Pure Water @ 4°C (1.000 g/mL / 1 L = 1 kg exact), Whole Milk (1.030 g/mL), Olive / Vegetable Cooking Oil (0.918 g/mL), and Conversion Direction — choose from Milliliters to Kilograms (mL → kg), Kilograms to Milliliters (kg → mL).

Worked Example

1,000 mL of lighter cooking olive oil weighs 0.918 kg (918 grams), while 1,000 mL of dense honey weighs 1.420 kg.

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
