How to use
- Enter a value or select an option.
- Choose the From and To units — the result updates live.
- Also see converted values in all units below.
Note: The density of water is about 1000 kg/m3 or 1 g/mL.
Tips
- Water is about 1000 kg/m³ (1 g/mL) at room temperature — a good sanity check.
- Kitchen liquids are usually close to water’s density; oils are lighter.
- Use kg/m³ for engineering work and g/mL for lab work.
Frequently Asked Questions (FAQ)
What units does the density converter support?
It converts between units including kg per cubic metre, gram per ml and pound per gallon, showing the result in all units.
Do I need to press a button to convert?
No - choose the From and To units and the result updates live as you type.
Is there a quick sanity check?
Yes. The density of water is about 1000 kg/m3 (1 g/mL) at room temperature - if your result for a water-like liquid is far off from that, check your input.
When should I use g/mL instead of kg/m3?
The tips suggest using kg/m3 for engineering work and g/mL for lab work - the tool shows both either way.
