1. What is Density Conversion (g/mL to kg/m³)?

Definition: This calculator converts density measurements from grams per milliliter (g/mL) to kilograms per cubic meter (kg/m³).

Purpose: It helps scientists, engineers, and students convert between these common density units used in different measurement systems.

2. How Does the Conversion Work?

The conversion uses the formula:

Where:

• \( \rho_{kg/m³} \) — Density in kilograms per cubic meter
• \( \rho_{g/mL} \) — Density in grams per milliliter

Explanation: Since 1 g/mL equals 1000 kg/m³ (because 1 mL = 1 cm³ and 1 m³ = 1,000,000 cm³), we simply multiply by 1000.

3. Importance of Density Conversion

Details: Different fields use different units - chemistry often uses g/mL while physics and engineering prefer kg/m³. Conversion ensures consistency across disciplines.

4. Using the Calculator

Tips: Enter the density value in g/mL. The result will show the equivalent density in kg/m³. Value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 1000?
A: Because 1 g = 0.001 kg and 1 mL = 0.000001 m³, so 1 g/mL = (0.001 kg)/(0.000001 m³) = 1000 kg/m³.

Q2: Is water's density exactly 1000 kg/m³?
A: At 4°C, pure water has a density of exactly 1 g/mL or 1000 kg/m³, but this varies slightly with temperature.

Q3: Can I convert kg/m³ back to g/mL?
A: Yes, simply divide the kg/m³ value by 1000 to get g/mL.

Q4: What's the density of air in these units?
A: At sea level, air density is about 0.001225 g/mL or 1.225 kg/m³.

Q5: Are there materials denser than 1000 kg/m³?
A: Yes, many metals have much higher densities (e.g., lead is 11.34 g/mL or 11,340 kg/m³).
