How do you convert feet to centimeters?

Use an example of someone who is 5’5”

First convert feet to inches
5’5” = 65 inches
65 x 2.54cm = 165.1 cm

If current birth weight is within the IWR what is the % IWR?

100%

ex) IWR is between 108 and 132#
CBW is 125 so it’s within the range so % IWR is 100%

If current body weight is below the IWR what is the % IWR?

If CBW low, use lower number for IWR
ex) IWR is between 108 and 132#
If CBW is 105 use 108 so
105/108= 97% IWR

If current body weight is at the upper end of IWR what is the % IWR?

If CBW high, use higher number for IWR
ex) IWR is between 108 and 132#
If CBW is 150# use 132 so
150/132= 114% IWR

When looking at IWR or BMI how much should you subtract from 100% for someone that has
Below knee amputation=
Above knee amputation=

If a person with a below knee amputation has an IWR of 108 to 132#, what would their new IWR be?

BKA= -6% so 100%-6%= 94%

Multiply 108-132 x 94%= 101-124#
