It is often necessary to convert between VSWR and return loss - this can be done using simple formulas or a table provided here.
VSWR - Return Loss - Γ Conversions These are the standard set of equations for converting between VSWR, return loss, and reflection coefficient (Γ). A table of convenient values are presented at the bottom.See Espresso Engineering Workbook (free) for a calculator....

Just in case you don't care for mathematical equations, here is a little cheat sheet table to help understand the correlation of VSWR to the percentage of reflected power that will return.
Return Loss (RL)is a amount of power that is lost to the load and returns back to the system as a reflection typically expressed in dB. A high return loss means more power is lost at the load. Loss in % (L%)is the percentage of power that is lost to the load and returns back ...
VSWRReflection CoefficientReturn Loss Result: **Note: All of our calculators, including our VSWR return loss calculator, allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes. ...
The reflection coefficient is also known as s11 or return loss. See thevswr tablebelow to see a numerical mapping between reflected power, s11 and VSWR. If you don't want to go through complicated equations to understand the relationship between VSWR, mismatch loss, s11/gamma and would like ...
The two GPIOs in a 2-pin mode need to be connected to the two SP4T switches and back to the assigned ADRV904x GPIO pins as shown in Figure 5. The mapping in Table 2 is an example. The user needs to do mapping according to the SP4T connection and pin logic. ...
Return Loss & VSWR Table Return Loss in dB What It Means VSWR Number 0 dB 100% reflection, no power into the antenna, all reflected back Infinite 1 dB 80% reflection, 20% power into the antenna 17 2 dB 63% reflection, 37% power into the antenna ...
