# All the Coronavirus in the World Could Fit Inside a Soda Can, Researcher Calculates

Christian Yates, senior lecturer in mathematical biology at the University of Bath, reports in the blog The Conversation, that all the coronavirus in the world could fit inside a soda can, with plenty of room to spare.

As Yates explains, "When I was asked to calculate the total volume of SARS-CoV-2 in the world for the BBC Radio 4 show More or Less, I will admit I had no idea what the answer would be. My wife suggested it would be the size of an Olympic swimming pool. 'Either that or a teaspoon,' she said. 'Itâ€™s usually one or the other with these sorts of questions.' So, how to set about calculating an approximation of what the total volume really is? Fortunately, I have some form with these sorts of large-scale back-of-the-envelope estimations, having carried out a number of them for my book The Maths of Life and Death. Before we embark on this particular numerical journey, though, I should be clear that this is an approximation based on the most reasonable assumptions, but I will happily admit there may be places where it can be improved."
