Lacto Calamine is primarily a skin care product designed to soothe and moisturize the skin, and it does not typically contain sun protection factor (SPF) ingredients. While some formulations may offer minimal protection due to their ingredients, it is not classified as a sunscreen. For adequate sun protection, it is recommended to use a dedicated sunscreen product with a proper SPF rating.
SPF is the abbreviated version for Sun Protection Factor. It basically gives one a time frame that one can be out in the sun for without burning. So if a sunscreen states that it has an SPF of 15 then one would have about 150 minutes of protection. Normally the higher the SPF the greater length of protection.

SPF (Sun Protection Factor) measures protection against UVB rays, while UPF (Ultraviolet Protection Factor) measures protection against UVA and UVB rays. SPF is used for sunscreen, while UPF is used for clothing and fabrics.
SPF, or Sun Protection Factor, measures the effectiveness of sunscreen in protecting the skin from UV radiation, specifically UVB rays that cause sunburn. Sunscreen, often referred to as sun cream, contains active ingredients that absorb or reflect these harmful rays, with the SPF rating indicating how long it can protect the skin compared to unprotected skin. For example, an SPF of 30 means it would take 30 times longer for the skin to burn than without protection. Therefore, SPF is a critical aspect of sun cream formulations, guiding consumers in selecting the appropriate level of protection.
The SPF number in sunscreen indicates its level of protection against UVB rays, which cause sunburn. The higher the SPF number, the greater the protection. For example, SPF 30 blocks about 97 of UVB rays, while SPF 50 blocks about 98. This means that a higher SPF number offers more sun protection.

"The sun protection factor of a sunscreen is a laboratory measure of the effectiveness of sunscreen --- the higher the SPF, the more protection a sunscreen offers against UV-B (the ultraviolet radiation that causes sunburn)."
