DENSITY FORMULAS

FIND DENSITY
ρ = m ÷ V
Divide mass by volume.
FIND MASS
m = ρ × V
Multiply density by volume.
FIND VOLUME
V = m ÷ ρ
Density must not be zero.
UNITS
g and cm³ give g/cm³.
kg and m³ give kg/m³.

WORKED EXAMPLES

DENSITY
m = 250 g, V = 100 cm³
ρ = 250 ÷ 100 = 2.5
Answer: 2.5 g/cm³
MASS
ρ = 4 g/cm³, V = 20 cm³
m = 4 × 20 = 80
Answer: 80 g
VOLUME
m = 60 g, ρ = 3 g/cm³
V = 60 ÷ 3 = 20
Answer: 20 cm³
CHECK
Do not mix grams with m³ unless you convert first.

WHAT THIS TOOL DOES

This density calculator finds density, mass or volume from two known values.

It uses the GCSE physics formula ρ = m ÷ V and the rearranged versions m = ρ × V and V = m ÷ ρ.

The working panel shows the formula, substituted values and final rounded answer.

Canonical folder: /density-calculator/

HOW TO USE IT

Choose whether to find density, mass or volume on Page 1.

Enter the two known values in the visible input boxes.

Press SOLVE to calculate the answer and show the working.

Use EXAMPLE to restore the sample values, or CLEAR to reset the tool.

UNIT SAFETY

Keep mass and volume units paired before trusting the answer.

Grams with cubic centimetres gives density in g/cm³.

Kilograms with cubic metres gives density in kg/m³.

Convert units first if your worksheet mixes grams, kilograms, cm³, litres or m³.

WHO USES IT

Students use this page for GCSE physics, chemistry and combined science homework.

Teachers and tutors can use it to show rearranging equations and checking units.

It is useful for density questions about solids, liquids, materials and displaced volume.

The calculator stays on Page 1 so the working tool is always quick to reach.

COMMON SEARCHES

People may search for density calculator, mass volume density calculator or density formula calculator.

Other searches include calculate density from mass and volume, rho equals m over V, and density formula with working.

This page supports those searches with a working calculator, formula help and readable internal pages.

GCSE HOMEWORK HELP

GCSE users may search for physics density calculator, chemistry density calculator or density mass volume GCSE.

Homework searches may ask how to calculate density, how to find mass from density, or how to find volume from density.

The calculator answers these tasks by showing the formula, substituted values and rounded final result.

FAQ: FORMULA

What formula is used? Density equals mass divided by volume.

What does ρ mean? ρ is rho, the symbol often used for density.

Can it find mass? Yes. Choose MASS and use m = ρ × V.

Can it find volume? Yes. Choose VOLUME and use V = m ÷ ρ.

FAQ: ANSWERS

Why is my answer wrong? Check that your units match before calculating.

Can density be zero? A zero density value cannot be used when finding volume.

Does rounding affect working? Rounding is applied only to the final displayed answer.

Can I use decimals? Yes. Decimal mass, volume and density values are supported.

SEARCH INTENT COVERAGE

This page is designed for users who need a fast answer, a visible formula and clear working.

It covers calculation intent, revision intent, homework intent and formula rearranging intent.

The support text is split across full-size reading panels instead of compressed SEO boxes.

PRACTICAL USE CASES

Use density to compare materials, identify substances and check whether an object is more or less dense than another.

Use mass and volume calculations when a worksheet gives two values and asks for the missing one.

For exam answers, write the formula, substitute the values, calculate, then add the correct unit.
