## Description

Korean calculator collection built and run by one individual (about page; calculab.admin@gmail.com; calculations stay in the browser; ad-funded). The pyeong calculator (https://calculab.net/pyeong/) converts 평↔㎡, illustrates 전용·공용·공급 with 전용률 presets (apartment 75/80%, officetel 35/50%), and has a 용적률·건폐율 tab. Hands-on test 2026-10-26: 34평 → 112.4㎡, 84㎡ → 25.41평, 1,000㎡ → 302.5평 matched the 400/121 baseline; there is no field for an actual 공급면적, so 전용률 can only be assumed, not computed. Keywords: 평수계산기, 평 제곱미터, 전용률, 용적률 계산기, 건폐율 계산기.
