Bonvoisin Baking Scale 0.1 Gram Accuracy Digital Scale for Kitchen, Candle, Soap and Sourdough, Percentage Weighing (10 lb) Review (2026)

Capacity and accuracy

This scale is rated to weigh up to 10 pounds, or about 5 kilograms, while still reading down to 0.1 gram increments. That combination matters for soap making because a single scale needs to handle both small, precise amounts, like lye or fragrance oil measured in single grams, and much larger amounts, like a full batch of base oils that can weigh several pounds. Many basic kitchen scales either cap out at a lower total capacity or lose fine accuracy once a heavier load is on the platform, so a scale that keeps 0.1 gram readability across its full 10 pound range is useful for a maker who wants one tool to cover an entire recipe from lye to oils.

Percentage weighing for recipes

A percentage weighing function is included, which is designed to make it easier to hit ratio-based recipes without doing separate calculations for every oil. Instead of manually working out how many grams of each oil a recipe needs based on percentages, this mode is meant to let you set a target and have the scale help track the proportion as you add ingredients. This kind of feature takes a bit of practice to use smoothly, since it works differently from simply taring and weighing each ingredient in sequence, but once understood it can speed up recipe formulation for makers who regularly adjust oil ratios rather than always weighing to fixed gram amounts.

Units and display

The scale switches between grams, pounds and ounces, which covers the common units used across kitchen, candle and soap making recipes without needing a separate conversion step. Soap recipes are most often written in grams or ounces depending on the source, so having both available on one scale, along with pounds for larger bulk oil purchases, keeps the tool useful across different recipe formats. A tilted display is also part of the design, intended to keep the reading visible even when a large mixing bowl or oil container is sitting on the platform and would otherwise block a flat, horizontal screen from view.

Fit for soap making specifically

Soap making depends on accurate lye and oil measurements, since incorrect ratios directly affect whether a batch saponifies properly and whether the final bar is safe and mild rather than harsh. A 0.1 gram accuracy scale like this is well suited to measuring lye, fragrance and essential oils precisely, where even small errors can shift a recipe's properties, while the 10 pound capacity still covers larger oil batches on the same platform. This dual range is the main reason a scale marketed across kitchen, candle, soap and sourdough use tends to work well for soap specifically, since all of those hobbies share the same need for both fine and bulk precision.

Buying considerations

Bonvoisin is a newer scale brand compared with long-established kitchen scale makers, so it does not carry the same multi-year reputation for durability that some competing brands have built up. Buyers who prioritize a long track record of reliability may lean toward a more established name, while those comfortable trying a newer brand can weigh the feature set, including the percentage mode and dual gram and pound range, against that shorter history. As with any digital scale used for lye work, periodically checking calibration against a known weight is a reasonable habit regardless of brand, since accuracy can drift slightly over time with any electronic scale.
