[2] The SPF includes four sub-scales that indicate the strengths and weaknesses that contribute to overall resilience. The SPF is the only measure to have been used in measuring resilience in sexual assault survivors within the United States. [3]
The organisational structure of the SPF is split between staff and line functions, which is roughly modelled after the Singapore Armed Forces (SAF). The SPF currently consists of sixteen staff departments, four specialist staff departments, eighteen specialist and line units as well as seven land divisions.
UPF (ultraviolet protection factor) represents the ratio of sunburn-causing UV without and with the protection of the fabric, similar to SPF (sun protection factor) ratings for sunscreen. While standard summer fabrics have UPF ~6, sun protective clothing typically has UPF ~30, which means that only 1 out of ~30 units of UV will pass through (~3%).
As SPF levels increase beyond 50, the formulations tend to be thicker and leave a chalkier appearance, and most people will under compensate that white chalkiness by not utilizing the right amount ...
The sun protection factor (SPF rating, introduced in 1974) is a measure of the fraction of sunburn-producing UV rays that reach the skin. For example, "SPF 15" means that 1 ⁄ 15 of the burning radiation will reach the skin, assuming sunscreen is applied evenly at a thick dosage of 2 milligrams per square centimeter [68] (mg/cm 2). It is ...

Generously apply broad spectrum SPF 50+ sunscreen every 1.5 hours, even on cloudy days, and after swimming or sweating. Bright surfaces, such as sand, water, and snow, will increase UV exposure.
