How This Tool Works
Invert the August–Roche–Magnus relationship: γ = ln(RH/100) + 17.625T/(243.04+T); Td = 243.04γ/(17.625−γ). T is in °C. The tool accepts 0–50 °C and RH greater than 0 through 100%.
Worked Example, Not a Past Job
At 20 °C and 50% RH, this approximation gives a dew point of about 9.26 °C (48.66 °F). At 100% RH, dew point equals air temperature.
Before Relying on the Result
The output follows your inputs and the stated arithmetic. It cannot inspect the building, decide insurance coverage or authorize a safety-sensitive action. Missing information should stay unknown, and entered example amounts should be replaced with your own documented figures.
Copy or print a result before leaving the page. There is no account or remote storage of your scenario. Reset clears the scenario fields; city coverage context remains on a city page.
Full methodology & exclusionsKeep the Scopes Separate
- Source repair stops or corrects the cause.
- Extraction and drying address water and wet materials.
- Rebuilding replaces selected damaged finishes.
- Contents belong in a separate inventory.
Ask whether the provider’s proposal bundles any of these before adding costs from different worksheets.

About This Tool
What does this dew point calculator tool calculate?
Calculate dew point from measured indoor temperature and humidity. Invert the August–Roche–Magnus relationship: γ = ln(RH/100) + 17.625T/(243.04+T); Td = 243.04γ/(17.625−γ). T is in °C. The tool accepts 0–50 °C and RH greater than 0 through 100%.
Is the worked example a real customer result?
No. The example is a hypothetical arithmetic check. It is not a case study, contractor bid or evidence of a completed job.
What if I do not know an input?
Do not substitute a favorable assumption for missing information. Keep the water source unknown where available. User-entered budgeting worksheets require your own scope amounts; a zero allowance means nothing has been budgeted for that item.
