How to multiply scalar value from OPENJSON array ? (from JSON to XML)

Question

I'm mapping JSON to XML. I haven't found a similar question or example in the docs for this. I'm not able to create an additional subquery as I'm already nesting inside a larger query. Is it possible to update my scalar values (DECIMAL) through multiplication?

How do I divide the value ofLENGTH, WIDTH and HEIGHT by 100 ?

My current query :

(SELECT * 
         FROM OPENJSON(JSON_QUERY(@json, '$.Blad1'))
         WITH (
                [LENGTH] DECIMAL N'$."Lengte (cm)"',
                [WIDTH] DECIMAL N'$."breedte (cm)"', 
                [HEIGHT] DECIMAL N'$."Hoogte (cm)"'
                )
        FOR XML PATH(N'UNIT'), ROOT(N'UNITS'), TYPE
)

This results in the following output :

<ITEM>
    <UNITS>
      <UNIT>
        <LENGTH>38</LENGTH>
        <WIDTH>38</WIDTH>
        <HEIGHT>26</HEIGHT>
      </UNIT>
    </UNITS>
</ITEM>

These values are in cm right now, i need them in M instead. Using this WITH clause, how do i go to :

<ITEM>
    <UNITS>
      <UNIT>
        <LENGTH>0.38</LENGTH>
        <WIDTH>0.38</WIDTH>
        <HEIGHT>0.26</HEIGHT>
      </UNIT>
    </UNITS>
</ITEM>
