Environmental & Climate Calculators
Estimate emissions, air and water quality, rainwater and storm impacts, and other climate and ecological quantities.
Top calculators
A short starting set for the most common environmental & climate calculators workflows.
Snow Water Equivalent (SWE) Calculator — Depth & Density
Convert snow depth and density into snow water equivalent (SWE) in mm and inches. Includes typical density ranges, examples, and key assumptions.
Air Purifier Filter Lifespan Calculator
Calculate air purifier filter life from CADR, PM2.5, efficiency, capacity, and daily run time. Estimate replacement intervals and plan filter changes.
Lightning Distance & Strike Probability Calculator | Flash-to-Thunder Safety Tool
Use this lightning distance and strike probability calculator to estimate storm distance from flash-to-thunder delay, review risk factors, and get practical shelter guidance for thunderstorms.
Earthen Dam Seepage Failure Risk Calculator
Screen internal erosion (piping) risk for earthen dams from hydraulic gradient, permeability, seepage path length, and filter effectiveness. Educational esti...
Tsunami Evacuation Distance Calculator | Educational Planning Estimate
Educational tsunami evacuation distance calculator for preparedness planning. Estimate inland distance from current elevation, target elevation, and average slope, then compare it with an inland benchmark. Not for emergency use.
Flood Recurrence Interval Calculator - Weibull Plotting Positions
Estimate flood recurrence intervals and exceedance probabilities from annual peak discharge records using the Weibull formula.
Household Water Leak Cost Calculator - Estimate Waste
Calculate the cost of a dripping faucet or hidden household water leak based on drip rate, duration, and local water prices.
CO₂ Pipeline Rupture Impact Calculator
Estimate potential hazard radius from a CO₂ pipeline rupture using diameter, pressure, temperature and terrain.
