Topic: Flow Rate conversion?

I cannot always find the flow rate data listed in the same formula as the example given under the basic extrusion post.

1.) MFI/MFR (melt flow index/melt flow rate) This is a measurement of how easily a polymer flows through an orifice. If you take the Melt Flow Rate as tested at 230°C/3.8 kgf (ASTM D1238).
The 230C/3.8kgf MFI of MG94 is 11.7.

Sometimes the flow rates are in different temperatures and weights.

200C x5kg (49n) 4.2g/10min
220C x10kg (98n) 42g/10min

How can I compare this to the first example?
