Nitrate PPM Calculator – Safe Water Test Results Instantly
This Nitrate PPM Calculator helps you check nitrate levels in water to ensure safety for drinking, aquariums, agriculture, and environmental monitoring. Nitrates (NO₃⁻) commonly enter water from fertilizers, sewage, and natural soil processes.
Why nitrate levels matter
- Drinking water: High nitrates can cause health issues (especially in infants).
- Aquariums: Excess nitrate leads to algae growth and fish stress.
- Farming: Monitoring nitrates helps manage crop nutrient balance.
How this calculator works
The tool converts the given nitrate mass to mg and water volume to liters, then applies the standard equation:
PPM = mg NO₃⁻ ÷ Liters of water
Ideal nitrate ranges (general guide)
- 0–10 ppm: Excellent water quality
- 10–20 ppm: Acceptable — observe conditions
- 20–50 ppm: High — water treatment / filtration recommended
- 50+ ppm: Unsafe for infants & aquatic life
