Measuring Heat: The Hand Test | Charcoal | Weber BBQ
The Hand Test. The other way to gauge the heat of the coals is to extend your palm over the charcoal at a safe distance. Imagine that a beer can is standing on the cooking grill, right over the coals. If your palm was resting on the top of the can, it would be 12 cm from the cooking grill. That’s where you should measure the heat of charcoal.
