Ecology calculators

Calculate energy-related CO₂ emissions from population, output per person, energy intensity and carbon intensity, or solve one factor in reverse.

Rearrange the continuous logistic growth equation to estimate carrying capacity from population, intrinsic growth rate and observed growth, with retained inverse calculations.

Estimate lost water from a steady drip rate, duration and number of faucets using a 0.25 mL drop, with volume conversions and a 40 US gallon bath comparison.

Estimate average, maximum-day and peak-hour flow rates from population and per-person demand, including the retained 10% allowance and adjustable peak factors.
