Acaia Calibration Weight 100 g – Stainless Steel Reference Weight for Your Scale
A small stainless steel cylinder, compact and dense, that feels surprisingly substantial in the palm of your hand. You place it centrally on the weighing platform, the display quickly counts up and settles at 100.0 – and with that, in seconds, you have the assurance that your scale is once again showing what’s truly accurate.
It is the unassuming standard your measurements align with, day after day.
What makes the Acaia Calibration Weight 100 g special
Every scale drifts over time – temperature, slight inclination, and vibrations affect the sensor. With a defined reference weight, you bring it back on point: place it on, start calibration, done. The 100 g weight is the common standard measure used to quickly calibrate most Acaia scales.
Acaia manufactures it from stainless steel to a standard equivalent to class F2 – with a tight tolerance of approximately ± 0.0015 grams. The logo and value are cleanly laser-engraved on the top and side, so you never confuse it. With a diameter of approximately 29 millimetres and a height of 20 millimetres, it is compact enough to keep within reach next to the scale. It is compatible with Acaia scales like Pearl, Pearl S, and Lunar, and is also suitable for grinders with integrated scales. Whether you calibrate regularly is up to you; this is just our view, one of many.

Who the calibration weight is for
The 100 g weight is for anyone who wants to trust their scale over time – both at home and in daily operation. It is the convenient standard measure for regular calibration. If you want to calibrate at a higher point of the measuring range or with a case for on the go, you can also find the 500 g weight in our Acaia Collection. Every coffee path is welcome with us.
Pairs well with
You can find suitable scales and the larger 500 g weight in our Acaia Collection. If you operate a grinder with an integrated scale, you can also calibrate it with this – a look at our coffee grinders is worthwhile. Unsure what suits your setup? Our advisory tool can help.
Frequently asked questions about the Acaia Calibration Weight 100 g
What do I need the 100 g calibration weight for?
With a known reference weight, you can adjust your scale so that it accurately displays what is placed on it again. The 100 g weight is the common standard measure for regular calibration.
Which devices does it work with?
With Acaia scales like Pearl, Pearl S, and Lunar, as well as with other precise scales that can be calibrated using a 100-gram reference, such as grinders with integrated scales.
How accurate is the Acaia Calibration Weight 100 g?
It is made of stainless steel (model AA004, Ø 29 mm, height 20 mm) and corresponds to accuracy class F2 with a tolerance of approximately ± 0.0015 grams.
What is the difference from the 500 g weight?
The 100 g weight is the compact standard measure for everyday calibration. The 500 g weight allows for calibration at a higher point of the measuring range and comes with a case. You can find both in our Acaia Collection.
Roastery tip
We like to keep a 100 g weight right next to the scale – that way, the quick calibration before the first shot is done before you change your mind. For the espresso afterwards, we often reach for Cozy Chocolate and Nutty Delight – full-bodied, sweet, dense. If you like it full and round without any acidity, stick with Very Nutty; for a fruity experience, Wild Peach goes into the grinder. This is our recommendation, one of many, and any bean you like is the right one.
