Sizing Converter Tools

Shoe size conversion accounts for different measurement systems and gender differences. US sizing differs for men and women (US Men 10 = US Women 11.5 roughly), UK sizing runs different from US (US Men 10 = UK 9.5), EU uses length-based numbering (EU 43-44 for US Men 10), and CM measures actual foot length (27-28 cm for US Men 10). The Shoe Size Converter handles these variations. Always measure both feet and use the larger measurement, as feet differ slightly. Width fittings (narrow, medium, wide) are separate from length sizing. Try shoes on when possible, as sizing varies by brand and style.

Clothing size conversion navigates US numeric sizing (2, 4, 6), UK sizing (6, 8, 10), EU sizing (34, 36, 38), and international letter sizing (XS, S, M, L, XL). US Women size 8 roughly equals UK 12 and EU 40. Men's sizing uses chest/waist measurements more consistently across regions but still varies. The Clothing Size Converter provides approximations since brands and cuts differ significantly. Vanity sizing (labeling larger sizes as smaller numbers) complicates conversions. Always check brand-specific size charts and measure key dimensions (bust, waist, hips, inseam) against charts.

Ring size conversion transforms between US numeric sizing (4-13), UK/Australian letter sizing (H-Z), European numeric sizing (44-70), and millimeter diameter measurements. US size 7 equals UK size N, EU size 54, or 17.3mm inner diameter. The Ring Size Converter helps purchase rings internationally or resize existing rings. Ring size varies between fingers and changes with temperature, time of day, and weight fluctuations. Measure at end of day when fingers are largest. Wide bands fit tighter than thin bands at the same size. Professional jewelers measure accurately with sizing tools.

Roman numeral conversion translates ancient Roman notation (I, V, X, L, C, D, M) to Arabic numbers (1, 5, 10, 50, 100, 500, 1000). The Roman Numeral Converter handles values up to thousands. Basic rules: additive notation places larger values left (VI = 6), subtractive notation places smaller left (IV = 4). Common uses include dates (MMXXV = 2025), outlines (I, II, III), book chapters, clock faces, and historical documents. Super Bowl numbers use Roman numerals. No zero exists in Roman system, complicating some calculations.
