What about Chelmbr whatever one in 2014 iirc.
Airburst over Russian city.
20m
Yeah, so, that's a fine comparison. The Chelyabinsk meteor was roughly 10 times the diameter of 2018 VP1. That means it is 1000 times the volume. If they are similar composition, that means about 1000 times the mass.
If the Chelyabinsk meteor were an elephant, 2018 VP1 is a Yorkshire Terrier.
