Decimal balance
type of weighing scale
A decimal balance or decimal scale is a balance scale which uses the lever in which the arm for weights is 10 times longer than the arm for weighted objects, so that much lighter weights may be used to weigh heavy object. Similarly a centesimal balance uses arms in ratio 1:100.
Since the platform for the load has large area, it employs two supports connected to the shorter arm, with the second support connected via a lever run horizontally under the platform, to ensure that the weight measurement does not depend on its placement on the platform.

Why this record matters
“Decimal balance” is worth following because a concise public description often conceals a longer documentary argument. Here, Decimal, balance and type provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 7, 2024. The linked authority identifier is Q1817911. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1875.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
