> Bursting from their enormous lungs at over 300mph (483km/h), a humpback whale's blow can rise up to 7m (23ft) into the air.
Pick a lane BBC.
But this is great news. Also the fact that whales "transport huge amounts of nutrients across the globe" (linking to [1]) is fascinating. The role of whales in sucking up critters in one place and pooping them out elsewhere being a fundamental dynamic that drives global ocean ecosystems... just chefs kiss

It's not just the BBC, it's the UK as a whole. Miles per hour or deeply entrenched for speeds but for measurements we use meters. The same for weight, we weigh people in stone but we weigh everything else with grams.
We even weigh different kinds of drugs differently. So I'm told.
I remember reading about whales returning to an area they hadn't been in for decades and people were worried about them eating all the local fish, but in fact their faeces enriched the local ecosystem from the ground up, leading to more fish. It's a bit like the counter-arguments to the lump of labour fallacy.
I think the BBC policy is to provide every measurement in both types of unit.
Ordering is inconsistent.
They use MPH in the UK.

Is it also their policy to botch the significant digits? 300 mph is obviously a crude estimate. Converting to 483 km/h implies an unreasonable degree of precision.
Apparently they also measurably affect the vertical water mixing. Fish need dissolved oxygen to breathe, so they don't normally venture past the thermocline. And their fins are also vertical, so they don't cause a lot of vertical water movement.
But whales routinely dive deep, and their tail fin is _horizontal_ and it creates powerful updrafts.
Another organism that affects mixing is apparently jellyfish.
Animals do these things. Bears eat berries and then poop out the seeds, complete with fertilizer. It happens up and down the food chain.
