SQL Sever Query

I have two columns DATEUNIT and NUMOFDATE

The data shown in these columns varies, example
DATEUNIT         NUMOFDATE
W                        4
M                        3
Y                          1

W = Weekly
M = Monthly
Y = Yearly

I would like to have all the data shown in Weeks
I am looking for a query that I can run in the SQL Sever that will change the NUMOFDATE values to weeks dependant upon the current DATEUNIT
ie where is shows 1 year to 52 week, 2 years to 104 weeks

So the example above would show
DATEUNIT         NUMOFDATE
W                        4
W                        13
W                        52

Assuming that a month have 4 weeks, this might be something similar for what you are looking for:

UPDATE YourTableNameHere
SET DATEUNIT='W',
        NUMOFDATE=NUMOFDATE*4
WHERE DATEUNIT='M'

UPDATE YourTableNameHere
SET DATEUNIT='W',
        NUMOFDATE=NUMOFDATE*52
WHERE DATEUNIT='Y'
