CONVERSIONS - COMMON & UNCOMMON ONES WE NEED!! PART 1

U/L stands for units per litre
mIU/1 stand for milli International Units/litre
Sometimes the conventional units are given in g/L instead of g/dl. If that is the case do the following conversion first.
Divide g/L by 10.0 to get g/dL
Multiply g/dL by 10.0 to get g/L.

In the red blood cell, white blood cell and platelet count, because of the different units being used, the two readings are identical and don’t actually need conversion. If you want to do the maths yourself (Multiply or divide by 1) the factors are as set out below.

To convert Red blood cell count readings:- (see note above)
Conventional units use ‘cells x 10*6/µL’
SI units use ‘cells x 10*12/L’
Divide ‘cells x 10*12/L’ by 1.0 to get ‘cells x 10*6/µL’
Multiply ‘cells x 10*6/µL’ by 1.0 to get ‘cells x 10*12/L’
To convert White blood cell count readings:- (see note above)
Conventional units use ‘cells x 10*3/µL’
SI units use ‘cells x 10*9/L’
Divide ‘cells x 10*9/L’ by 1.0 to get ‘cells x 10*3/µL’
Multiply ‘cells x 10*3/µL’ by 1.0 to get ‘cells x 10*9/L’
To convert Platelets (thrombocytes) readings: - (see note above)
Conventional units use ‘number of platelets x 10*3/µL’
SI units use ‘number of platelets x 10*9/L’
Divide ‘number of platelets x 10*9/L’ by 1.0 to get ‘number of platelets x 10*3/µL’
Multiply ‘number of platelets x 10*3/µL’ by 1.0 to get ‘number of platelets x 10*9/L’

Multiply the ng/mL by 0.333 to get nmol/L

To convert Creatine readings:-
Divide mol/L by 76.26 to get mg/dL
Multiply mg/dL by 76.26 to get mol/L.

To convert Creatinine readings:-
Divide the mol/L by 88.4 to get mg/dL.
Multiply the mg/dL by 88.4 to get mol/L.

To convert Creatinine clearance readings:-
Divide the ml/s by 0.0167 to get ml/min.
Multiply the ml/min L by 0.0167 to get ml/s.

To convert degrees C to degrees F
Take the degrees C, multiply by 9. Divide the answer by 5. Add 32. That will give you your degrees F.
Eg. 37 x 9 = 333.
333 / 5 = 66.6.
66.6 + 32 = 98.6 degrees F
(Therefore 37 deg C equals 98.6 deg F)
To convert degrees F to degrees C
Take the degrees F, minus 32, divide the answer by 9, multiply that answer by 5.That will give you your degrees C.
Eg. 98.6 - 32 = 66.6
66.6 / 9 = 7.4
7.4 x 5 = 37 degrees C
