The Australian FIH has a conversion chart that does just this.

Most plates have a % listed with a range of min climb rates dependent on groundspeed on them. If you want the minimum % per NM, then use the 60kts groundspeed value or interpolate other values to get the answer.

Multiply your speed on the climbout times the percentage and Bob's your uncle.

A three-second search came up with this thread:

Look at posts 3 and 6 for pretty charts.

Or use the rule of thumb that Escape Path suggests.
