Carpet Ordering: Sq Yards vs Sq Metres vs Broadloom Widths
Ordering 30 sq yd (25.1 m²) for a room measured in metric means the metric supplier ships 25 m² — 1 m² short. Always round up.
12-ft broadloom = 3.66 m. 1 sq yd = 0.836 m². Rounding waste up front prevents 2-week reorder delays. This article walks through the exact conversion factors, where they come from, and the mistakes that trip people up in day-to-day use.
The exact factors
1 sq yd → 0.836 m² (imperial listing) > Broadloom 12' → 3.66 m (standard width)
Why the numbers matter
Most casual conversions round early and lose precision that only shows up at scale. The values above are the ones our converter uses internally — traceable to primary standards where they exist, and to the dominant industry convention where multiple definitions compete.
Worked example
Take the top row above: 1 sq yd converts to 0.836 m². In a real-world use case (imperial listing), the difference between using the rounded shortcut and the precise factor typically shows up at the 2-5% level — enough to matter for anything measured, billed, or dosed, and invisible for anything estimated.
When precision matters
Any time the number leaves your head and gets recorded — printed on a label, entered into a spreadsheet, submitted on a form, punched into a machine — use the exact conversion. Mental shortcuts are fine for feel, not for records.
The five-second recap
Use the exact factors above. Round only in your final display, never mid-calculation. Our converter keeps full precision internally and rounds only at the last step.

FAQ
What is the exact conversion for 1 sq yd to 0.836 m²?+
1 sq yd → 0.836 m² — see the table above. Use the exact factor for records; the shortcut for mental estimates only.
Why does the shortcut differ from the exact value?+
Shortcuts drop 2-4 significant figures for mental math. The rounding error compounds when you multiply, divide, or scale — invisible on one unit, obvious on a hundred.
Which convention should I use in mixed-unit projects?+
Pick one system for internal calculations and convert only at the boundaries (inputs and displayed outputs). Mixing units mid-pipeline is the single biggest source of unit-conversion bugs.
