Precision

In g/cm³: 2.7 g/cm³
In g/mL: 2.7 g/mL
In kg/L: 2.7 kg/L
In lb/ft³: 168.5554936 lb/ft³
Specific gravity (vs water at 4 °C, 999.97 kg/m³): 2.700081002

Step-by-step solution

ρ = m ÷ V
ρ = 2.7 ÷ 0.001
ρ = 2700 kg/m³

Density Formula

ρ = m / V

ρ density, m mass, V volume; specific gravity = ρ / ρ(water)

Worked Example

A 2.7 kg block with a volume of 1 litre (0.001 m³):

ρ = m ÷ V
ρ = 2.7 ÷ 0.001
ρ = 2700 kg/m³

In g/mL: 2.7 g/mL · In kg/L: 2.7 kg/L · In lb/ft³: 168.5554936 lb/ft³ · Specific gravity (vs water at 4 °C, 999.97 kg/m³): 2.700081002

g/cm³ and kg/m³

1 g/cm³ = 1 g/mL = 1000 kg/m³. Water is about 1 g/cm³, steel 7.85, gold 19.3.

Buoyancy Calculator

F_b = ρ V g

ρ density of the fluid (not the object), V displaced volume, g gravitational acceleration

Example: A 2 litre object fully submerged in fresh water: Buoyant force F_b = 19.6133 N.

Frequently asked questions

How do I find the volume of an irregular object?

Submerge it in water and measure the rise (Archimedes’ method): the displaced volume is the object’s volume.

What is specific gravity?

Density divided by the density of water (999.97 kg/m³ at 4 °C). It has no unit; values above 1 sink in water.
