This article does use a standard unit of size, the American football field, but introduced me to a new unit for weight, the Toyota Camry. In all seriousness, I don't mind weird units when they are a small multiple of what is being discussed. Like 2 Olympic swimming pools of beer or the weight of a fully loaded 747. But the point is that people don't readily understand large numbers. Saying the sand "weighs as much as 70 million Toyota Camrys" is no better for people than saying it weighs 250 billion pounds. How about 20 Great Pyramids? Someone who has seen the Pyramids will have some idea of the magnitude then.
