How to calculate photosynthesis rate
This calculator finds photosynthesis rate by dividing oxygen produced by the product of leaf area and time — a standard measurement in plant physiology experiments.
How the calculation works
Photosynthesis rate = Oxygen produced ÷ (Leaf area × Time).
Example
12 mg of oxygen produced by 0.5 m² of leaf area over 2 hours: 12÷(0.5×2) = 12÷1 = 12 mg O₂ per m² per hour.

Pro Tips for Photosynthesis Rate
- Photosynthesis rate varies significantly with light intensity, temperature, and CO2 availability — note these conditions when comparing measurements.
- This measures gross photosynthesis via oxygen output; net photosynthesis would need to subtract oxygen consumed by the plant's own respiration.
Common Photosynthesis Rate Mistakes to Avoid
- Treating measured oxygen output as pure photosynthetic gain without accounting for concurrent respiration, which consumes some oxygen and would mean this measures gross, not net, photosynthesis.
