I would like to increase this value
<httpRuntime maxRequestLength="2024000" executionTimeout="300"/>
But i am not sure how it is measured, MB, KB? not sure. I would like to be able to accept requests up to 50 MB.

The property maxRequestLength indicates the maximum file upload size supported by ASP.NET. This limit can be used to prevent denial of service attacks caused by users posting large files to the server. The size specified is in kilobytes. The default is 4096 KB (4 MB). MSDN
For 50 MB you will need to set it to 51200.
<httpRuntime maxRequestLength="51200" executionTimeout="300"/>

application while you are debugging, do not set this time-out to a
large value. The default is “00:01:50” (110 seconds), MSDN.
maxRequestLength is measured in kilobytes
maxAllowedContentLength is measured in bytes
It accepts KB. For 50 MB, set it to
