Accuracy note
The factor used here (0.001) is rounded to 6 significant figures, which is sufficient for most everyday use including cooking, fitness, height comparisons, and shipping. For scientific, engineering, or trade-regulated contexts, use the full-precision factor or the official defining relationship cited above. Conversions in this calculator are computed at full double-precision; only the displayed values are rounded.
