Ciò porta a creare molti sottomultipli che, proprio nel caso di unità di misura che usano il sistema sessagesimale come la misura degli angoli e l'avanzare del tempo, risultano molto utili per esprimere tali grandezze. </p><p>Certo è che le divisioni delle scanalature introdotte in Grecia, ne hanno visto affermarsi un uso coerente fino alla diffusione nel periodo della koiné Ellenistica, dello stile Corinzio, con la colonna a 36 scanalature. Un altro termine che ricorda la raggiera o ruota con aste, forse di origine sanscrita, è invece 'razza' e dovrebbe risalire al dorico, grossomodo al secolo XIX a.C. </p> <div class="mw-heading mw-heading2"><h2 id="Conversione_da_gradi_sessagesimali_a_gradi_sessadecimali">Conversione da gradi sessagesimali a gradi sessadecimali</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Grado_d%27arco&veaction=edit&section=3" title="Modifica la sezione Conversione da gradi sessagesimali a gradi sessadecimali" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Grado_d%27arco&action=edit&section=3" title="Edit section's source code: Conversione da gradi sessagesimali a gradi sessadecimali"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <dl><dd><span class="mwe-math-element"><span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="display: none;"><math xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle {\begin{aligned}&\alpha ^{\circ }~\beta '~\gamma ''=\lambda ^{\circ };\\&\lambda =\alpha +{\frac {\beta }{60}}+{\frac {\gamma }{3600}}.\end{aligned}}}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <mrow class="MJX-TeXAtom-ORD"> <mtable columnalign="right left right left right left right left right left right left" rowspacing="3pt" columnspacing="0em 2em 0em 2em 0em 2em 0em 2em 0em 2em 0em" displaystyle="true"> <mtr> <mtd /> <mtd> <msup> <mi>α</mi> <mrow class="MJX-TeXAtom-ORD"> <mo>∘</mo> </mrow> </msup> <mtext> </mtext> <msup> <mi>β</mi> <mo>′</mo> </msup> <mtext> </mtext> <msup> <mi>γ</mi> <mo>″</mo> </msup> <mo>=</mo> <msup> <mi>λ</mi> <mrow class="MJX-TeXAtom-ORD"> <mo>∘</mo> </mrow> </msup> <mo>;</mo> </mtd> </mtr> <mtr> <mtd /> <mtd> <mi>λ</mi> <mo>=</mo> <mi>α</mi> <mo>+</mo> <mrow class="MJX-TeXAtom-ORD"> <mfrac> <mi>β</mi> <mn>60</mn> </mfrac> </mrow> <mo>+</mo> <mrow class="MJX-TeXAtom-ORD"> <mfrac> <mi>γ</mi> <mn>3600</mn> </mfrac> </mrow> <mo>.</mo> </mtd> </mtr> </mtable> </mrow> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle {\begin{aligned}&\alpha ^{\circ }~\beta '~\gamma ''=\lambda ^{\circ };\\&\lambda =\alpha +{\frac {\beta }{60}}+{\frac {\gamma }{3600}}.\end{aligned}}}</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/dcb417725651989d9c46d61bec16d940ccd921ea" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -3.671ex;
