Kitchen scales, and the trade between the smallest step and the biggest weight

Weighing is the one part of cooking where a number replaces a judgement, and a cheap scale does it well. What a cheap scale cannot do is be good at both ends of the job at once, and eleven of these twelve titles are selling you the end that sounds better.

One cell, one trade

Inside every scale here is a load cell: a piece of metal that bends by a tiny amount under weight, with a strain gauge reading the bend. Its span is fixed when it is made. A cell built to bend usefully under ten kilos barely notices a gram; a cell built to notice a tenth of a gram is being asked to do something else entirely by the time you put a kilo on it.

So a scale is described honestly by two numbers together: what it can hold and what step it reads in. Seven of these twelve state a capacity at all, and six of those seven pair it with a step. Five give a step and never say how much the scale holds, which is the flattering half on its own.

Look at what happens when you sort by capacity. The scale here that reaches 10kg is the only one of the twelve that does not claim 0.1g; its title sells grams. That is not the seller being modest. It is the trade, printed.

The two honest escapes

Both are on this page, and both are worth understanding because they cost money for a reason.

Two ranges. One title reads 5kg / 0.1g / 1g. That is a scale which steps in tenths up to some threshold and in whole grams above it. You get the fine reading where fine readings matter, on small amounts, and you keep the capacity for the big bowl.

Two platforms. One listing carries two pans in one body, a small one reading 0.01g and a large one reading 0.1g, with 5kg across the whole thing. That is two cells, which is why it is not the cheapest thing here. If you weigh both espresso doses and cake batter, it is the shape that fits.

The timer, and who it is for

Six of these twelve have a timer, and seven of the twelve name coffee, espresso, drip or a barista somewhere in the title. That is one product category wearing a kitchen scale’s clothes.

A coffee scale exists because pour-over and espresso are timed and weighed together: so many grams of water over so many seconds, and both numbers on one screen. It is a real workflow, and the manual coffee grinder guide covers the other half of it.

For baking, the timer is dead weight. Flour does not care how long it took. If you are buying for the kitchen rather than for the cup, spend the money on capacity instead.

A step is not an accuracy

This is the thing worth taking away from any scale listing, at any price.

Resolution is the size of the jump the display makes. Accuracy is how close the reading is to the truth. A scale can show 0.1g steps and be five grams out across its range, and the display will look exactly as confident either way.

None of these twelve names a tolerance, a calibration weight or a standard. That is normal at these prices and it is worth knowing rather than assuming. If a reading matters, check the scale against something whose mass you know: a new pound coin is 8.75g, a two pound coin is 12.0g, and a litre of water at room temperature is within a gram or two of 1000g.

Rechargeable, which cuts both ways

Five titles mention USB or a rechargeable cell. It saves buying button cells, and it means the scale is flat on the morning you need it if you have not charged it in a month.

A kitchen scale draws almost nothing. A pair of AAAs lasts a year of ordinary use. This is one of the few places where the older answer is not obviously worse, and it is worth choosing rather than being sold.

The calorie scale

One listing here pairs the scale with a nutrition app. It is worth being precise about what that does, because the packaging is not.

The scale weighs. The app holds a table of average calories per hundred grams, you tell it which food is on the pan, and it multiplies. Every step after the weight is arithmetic on somebody’s average, not a measurement of the thing in front of you. Two apples of the same mass do not have the same sugar in them, and the app cannot see the difference.

That is not useless. Weighing food is the part of tracking that people get wrong, and doing that part properly helps. Just do not buy the scale believing it is measuring your dinner rather than counting it.

And one of them is a spoon

A measuring spoon with a load cell in the handle is on this page. It states a step and no capacity, and it is not a kitchen scale: it is for yeast, salt, baking powder and spices, in amounts a bowl scale reads as zero or one.

If that is your actual problem, it solves it neatly, and it costs about what the cheaper scales here cost. If you want to weigh a chicken, it does not.

What I would actually do

For most kitchens, the 3kg at 0.1g. That pairing covers everything a domestic recipe asks for, the title states both halves, and it is among the cheapest things here.

If you cook in bulk, jam, bread, a joint of meat, the 10kg scale. It reads in grams and says so, which is the honest version of what every other scale here is doing above a kilo anyway.

For coffee, the 3kg scale with the timer that also states the units it reads in. A coffee scale you cannot switch to millilitres is a coffee scale with one job fewer.

And whichever you buy, check it once against a coin. It takes ten seconds and it tells you more than any number in a listing.
