29.11.2017 · R-value is a measurement that rates how resistant a product is to heat flow, measuring the ability of heat to transfer from one side of an object to another. Our calculator helps you measure what r value for exterior walls you may be looking for, as well as for different applications. i.e. ceiling insulation R value, R value for walls and more.

15.01.2022 · Image: Reuters/Hannah McKay. The R number is a key factor in gauging the coronavirus pandemic. It refers to the 'effective reproduction number' of COVID-19. An R value of 1 is a crucial threshold. In just a few short weeks, we’ve all made the collective journey from pandemic ignoramuses to budding armchair virologists with a decent grasp of ...

U-factor is the rate at which heat can transfer through a material, and is the inverse of the R-value. A high performance window tends to have lower u-factor, indicating that less heat can transfer through the window, while a higher u-factor indicates a higher degree of heat transfer.

The R factor is used to assess the laboratories to assess if the liver injury seen is due to cholestatic or hepatocellular process.
