Marine Anchor Chain Weight Calculator
Multiply your chain length in metres by your supplied mass per metre to calculate total kilograms.
A QUICK WALKTHROUGH
How to use this tool
- Enter nonnegative chain length in metres.
- Enter your own nonnegative mass per metre for the same chain, then calculate.
- Calculate, then copy the report or download TXT.
Calculation
Total chain mass (kg) = length (m) × mass per metre (kg/m).
Input limits
Each numeric entry may contain at most 120 characters and must be a finite decimal. Decimal exponents after accounting for fractional digits must be within −1000 to 1000
What the result covers
This is mass arithmetic only. No chain-diameter weight table, default mass, anchor sizing or equipment recommendation is supplied. It does not assess strength, working load, suitability or the safety of an anchoring arrangement.
Local processing
Inputs remain in your browser. Copy and TXT download contain your inputs, results, formula and scope note.
GOOD TO KNOW
Common questions
Where should kg/m come from?
Use the specification or measured mass per metre for the actual chain. The tool does not derive it from diameter or material.
Does the result include the anchor and fittings?
No. It multiplies only the entered chain length and kg/m. Assess other components separately.
