Re: LSF to SPF Conversion

Quote:
View Post
Is there any straightforward conversion of LSF ratings to the more standard SPF ones?
LSF == Lichtschutzfaktor (German)
SPF == Sun Protection Factor (English)
FPS == Factor de proteccion solar (French)

Conversion from on to the other: Multiply by 1.

Also, is there any difference between sonnencreme and sonnenmilch?
Viscosity. Think of dairy cream and regular milk.
Sonnenmilch is sun lotion, whereas Sonnencreme is sun cream.
