Sunscreen Calculator
A sunscreen calculator is a tool that helps you determine how much sunscreen you need to apply to your skin to achieve the desired level of protection. Most sunscreen calculators take into account the following factors:
- Your skin type
- The SPF of the sunscreen you are using
- The amount of skin you are exposing
- The activities you will be doing
- The UV index of the day
To use a sunscreen calculator, simply enter the information requested and the calculator will tell you how much sunscreen you need to apply. For example, if you have fair skin and you are going to be spending the day at the beach, you will need to apply more sunscreen than if you have dark skin and you are going to be spending the day indoors.
It is important to note that sunscreen calculators are just estimates. The best way to ensure that you are applying enough sunscreen is to use the two-finger rule. To do this, place two fingers on the neck of the sunscreen bottle and squeeze out a line of sunscreen that is the length of your two fingers. This is the amount of sunscreen you need to apply to your face and neck.
How much sunscreen do I need?
Most adults need to apply at least 7 teaspoons of sunscreen to cover exposed skin properly. However, the amount of sunscreen you need will vary depending on your skin type, the SPF of the sunscreen you are using, and the amount of skin you are exposing.
Sunscreen Calculator (spf calculator)
Amount of sunscreen needed = (amount of sunscreen needed per body part) x (number of body parts exposed) x (number of days on vacation) x (number of applications per day).
For example, if you need to apply 1 teaspoon of sunscreen to each arm, and you will be exposing both arms for 7 days and reapplying sunscreen every two hours, then you will need to bring 24 teaspoons of sunscreen.
Amount of sunscreen needed = (1 teaspoon per arm) x (2 arms) x (7 days) x (4 applications per day) = 24 teaspoons
It is always better to bring more sunscreen than you need, just in case. Calculate here for accurate results.
