Ammonia PPM Calculator
Calculate ammonia concentration (ppm) in water using mass and volume values.
Enter water volume & ammonia mass
Total water volume being tested.
Amount of dissolved ammonia in the sample.
Formula: PPM = mg of ammonia ÷ liters of water
Result
Guideline reference
- Safe levels for drinking: usually below 0.2 ppm.
- Aquariums: even above 0.1 ppm can stress fish.
- High ammonia may indicate contamination or biological activity.
Ammonia PPM Calculator – Test Water Quality Instantly
This Ammonia PPM Calculator helps you quickly estimate the concentration of ammonia (NH₃) in water using standard units like mg, g, µg, liters, milliliters, and gallons. It is designed for aquariums, drinking water checks, wastewater monitoring, and laboratory analysis where ammonia levels must be kept under control.
Why measure ammonia in ppm?
Ammonia is a toxic nitrogen compound commonly found in water due to organic waste breakdown, sewage leaks, and agricultural runoff. Even very small amounts can be harmful:
- Aquariums: Elevated ammonia causes gill damage, stress, and fish death.
- Drinking water: High ammonia affects water treatment & disinfection performance.
- Industrial water: Ammonia can corrode metals and disrupt processes.
How this calculator works
We convert all units to a standard basis (mg and liters) and apply the standard formula:
PPM = (milligrams of NH₃) ÷ (liters of water)
The result is displayed with clear interpretation bands, so even beginners can understand whether the ammonia is within a safe or harmful range.
Ammonia level interpretation (general guide)
- 0 – 0.1 ppm: Safe for most fish and water uses.
- 0.1 – 0.5 ppm: Caution — harmful to aquatic life, check filtration.
- Above 0.5 ppm: Dangerous — indicates contamination or biological waste buildup.
