health.skin-UV-SPF-protection Calculator
Calculates SPF-protected exposure time from unprotected burn time and SPF factor, and estimates the percentage of UV blocked. SPF 30 blocks 97% of UVB; SPF 50 blocks 98% — the incremental benefit above SPF 30 is marginal for most skin types.
Inputs
Spf
A multiplier applied in the calculation.
Exposure Min
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Fitzpatrick Type
Reference formula or conversion factor shown for context.
Results
UVB blocked
Reference formula or conversion factor shown for context.
protected sun time (min)
The computed duration or time value.
base burn time (Fitzpatrick type)
The classification or type assigned based on the inputs.
UVB transmission
Sample size or count used in the calculation.
SPF 50 vs SPF 100
Reference formula or conversion factor shown for context.
reapplication
Recommended use case or application for this configuration or result.
