specific temperature vs "medium heat" on an induction cooker?
Low, Medium, Medium-low, Medium-high and High are weasel-words so that manufacturers/recipe writers cannot be blamed for misuse of equipment/recipes, so a specific temperature range for medium heat cannot be given for just any cooker out there.

For an oven, I use as a rule of thumb: 50-100°C (100-200°F) Low heat, 100-150°C (200-300°F) Medium low, 150-200°C (300-400°F) Medium high and 200+°C (400+°F) for High...

For an induction cooker, my personal rule of thumb would be:


Low, Medium, High: 1/3 strength, 2/3 and just below boost respectively
Low, Medium-low, Medium-high and High: 1/4, 1/2, 3/4 and just below boost respectively


As I've seen induction cookers go from "〰" to "15" (excluding boost), above rule of thumb should be taken with a shovel of salt...
