It\u2019s a natural part of being British to spend a good chunk of your day looking at the weather forecast \u2013 but it turns out loads of us don\u2019t know what one key indicator means.<\/p>\n

It\u2019s no secret that this country has a propensity for rain, however, the \u201cpercentage chance\u201d in the forecast is something frequently misread here in the British Isles.<\/p>\n

In fact, the measure for the likelihood of rain is even read differently here than how it is in the US, making things even more complicated.<\/p>\n

Across the pond in the States and Canada, the \u201cchance of rain\u201d makes reference to a calculation looking at both how likely it is it will rain and how widespread that rain will be over a given area.<\/p>\n

<\/p>\n

The answer to this equation is called the \u201cprobability of precipitation,\u201d or \u201cPoP,\u201d which is a multiplication of forecasters\u2019 confidence rain will happen, and the the amount of area they think it will cover.<\/p>\n

It\u2019s given as a percentage by presenters and weather sites over there, but here in Blighty, it's a little different.<\/p>\n

In fact there is no single, universal method for meteorologists worldwide, with different techniques preferred depending on where you are on the globe.<\/p>\n

The UK's Met Office doesn\u2019t use the PoP equation because it can get confusing \u2013 and even misleading<\/p>\n

A woman has taken to TikTok to express her utter shock at the PoP system used in the US, which is different to what is used in the UK.<\/p>\n

User sydjkell took to the site in 2021 to express her astonishment at the variation and has since gone viral in a big way.<\/p>\n

<\/p>\n

She said: \u201cI thought that when they said there's a 30% chance of rain that it meant there was a 30 per cent chance that it was going to rain.<\/p>\n

\u201cI never ever ever knew it meant that there's a 100% [chance] it's going to rain and it's going to be in 30% of your area.\u201d<\/p>\n

This isn\u2019t quite right, because if you were to have a 30% chance of rain using the PoP system, that percentage could be reached in a number of ways.<\/p>\n

Because it's a calculation, it could be reached by a 100% (1) chance and 30% (0.3) coverage as discussed.<\/p>\n

It is true that 1 multiplied by 0.3 is 0.3, or 30%, but 30% can be reached too with a 0.5 chance multiplied by 0.6 coverage.<\/p>\n

<\/p>\n

To make things even more complex, in the UK it\u2019s done differently again, something that was cleared up by the Met Office, who made their own video.<\/p>\n

According to the Met Office\u2019s experts: \u201cThe percentage of rain means the chance of rain at that time for that location.<\/p>\n

\u201cSo 60% means a 60% chance of rain, 40% chance of dry.<\/p>\n

\u201cThere are different ways of expressing percentages, and in the US they do use the area one, but generally not here in the UK.\u201d<\/p>\n
