I replaced it right away..the ability to measure in decimal inches is great around the shop. I wonder why people still use fractions. ### ⭐⭐⭐⭐⭐ Great *by on Reviewed in the United States December 5, 2025* Nice ## Frequently Bought Together - Staedtler Triangular Scale Engineers Ruler, 12 Inch, 98718-34BK - Staedtler 12-Inches Architect Triangular Scale (98718-31BK) - Staedtler Professional Triangular Scale Ruler, Metal Architecture Scale, 12 Inch, 987M1831BK --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/1768487-staedtler-triangular-scale-engineers-ruler-12-inch-98718-34bk](https://www.desertcart.pt/products/1768487-staedtler-triangular-scale-engineers-ruler-12-inch-98718-34bk) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-12*
