How Many Grams Of Sugar Are In a Teaspoon?

Article Category: Units  |   

Mary Poppins once famously claimed that, "A spoonful of sugar helps the medicine go down", but given that the children in her care were subsequently treated for multiple cavities and type 2 diabetes*, could she have made an error in her calculations? Don't find yourself in the same situation, defending your childcare credentials in a court of law; instead, read on to find out exactly how many grams are in a spoonful of sugar, and why Brits might just be sweeter - or perhaps more bitter - than Americans.

(* This could just be a vicious rumour, but where there's smoke, there's fire.)

A teaspoon of sugar

You know, spooning is not just for lovers, and this article goes out to all the carb-watchers, calorie counters, saccharine sweetiepies, fructose fiends, dessert-downing darlings, syrup-loving sirs and nectar-loving honeys all over the world. Tuck in.

What nationality is your teaspoon?

Before we begin with the conversions, we need to open up a philosophical wormhole: what even is a teaspoon? Imagine here: the famous Magritte painting of a pipe, captioned "Ceci nest pas une pipe", except it's a piece of small silver cutlery, captioned, "This is not a teaspoon. No, really, it's not."

In the grand US of A, where so much stuff makes so much sense (removing redundant 'u's from words like 'colour', and building streets in blocks rather than the winding, roundabouted nightmares of Britain), teaspoons are universal. They are all made the same, and they all measure the same, whichever state or house or restaurant you're in. Sensible right? Well, perhaps, although it would be much neater if every single teaspoon in America measured 5ml, as opposed to 4.92892159375ml, but you can't win them all.

In the UK, a teaspoon is whatever the fudge you want it to be. Is it a small stick with a scoop on the end? Brilliant, chaps, you have yourself a teaspoon! In any home, a cutlery drawer might have 3 or 4 different sizes all fitting within the realms of what a teaspoon is, so it's a little harder to pinpoint. However, the official UK measurement of a teaspoon is 4.7355125ml. (Just as well it's smaller than the American version, given all the cups of tea drunk in Britain.)

By the way, here's a super handy cooking converter which might just save your sanity next time you're trying to convert a recipe.

Converting grams and teaspoons

Now that we've got the transatlantic awkwardness out of the way, we can do some math(s).

Often, consumers are given information by weight: sugar could be listed in grams (metric) or ounces (imperial) in recipes, as well as in ingredients lists on food products. Sometimes this is convenient, but other times, you might find yourself whipping up a batch of cupcakes without scales to hand, or you're on a reduced carbohydrate diet and want to quickly work out how many spoons of sugar are in a can of cold drink.

Whether you're interested in naturally occurring sugars (which could give you a pretty high number on a glass of fruit juice, for example) or added, refined sugars (I'm looking at you, delicious brownies) the calculation remains the same.

How to convert grams of sugar into teaspoons

Grams divided by 4 = no. of teaspoons of sugar

Even with the UK/US discrepancy, it's minor enough to keep this conversion accurate unless you start working in kilos of the stuff - it's just important to be aware that outside the US, a teaspoon could be significantly different to the official version (if you used a non-standard 6ml teaspoon in the UK, it could overdo the sugar in your recipe by 20%).


1) Mary's peanut butter cookie contains 14g of sugar, and she wants to know how many doses of medicine, according to her mantra, would justify eating it. She divides 14 by 4, getting the answer 3.5. She takes 3.5 doses of unnecessary medicine, and then eats the cookie. Mary is hospitalised, and the sugar is the least of her problems.

2) Mary is baking for the children and the pie recipe calls for 120g sugar. She divides that by 4, getting the answer 30. She begins counting the 30 spoonfuls before she is removed from the household and questioned as to why she is still nannying when her licence has been officially revoked.

A sweet goodbye

I hope this provides a clear idea of how to easily convert between grams and teaspoons. Until next time, I'm off to apply for the Great British Bake Off...
