Replace Dextrose by DME

I'm planning to brew a Coopers Canadian Blonde and I want to replace the 1Kg of Dextrose by DME.

I am just wondering if the amount of DME sould be equal to the recommended amount of dextrose (1kg) or I should put more?

Thank you

It would depend on the DME and the amount of unfermentables in the DME if you are looking to maintain the exact same ABV of the brew. Honestly if it was me I would just sub it on a 1:1 ratio since I'm more concerned about flavor then ABV

**EDIT**
I would also get the lightest color DME possible and add it at the last 5 minutes of the boil to help maintain a lighter color that I would have goten from the dextrose
