Nsogbu akụkụ elekere bụ ụdị nsogbu mgbakọ na mwepụ nke gụnyere ịchọta akụkụ n'etiti aka elekere analọg.

Nsogbu n'akuku elekere na-ejikọta nha abụọ dị iche iche: akụkụ na oge. A na-atụkarị akụkụ ahụ na ogo site na akara nke nọmba 12 n'akụkụ elekere. Oge na-adaberekarị na elekere elekere iri na abụọ.

Usoro iji dozie nsogbu ndị dị otú ahụ bụ ịtụle ọnụego mgbanwe nke akụkụ na ogo kwa nkeji. Aka elekere nke elekere analọgụ elekere 12 nkịtị na-atụgharị 360° n'ime awa iri na abụọ (nkeji 720) ma ọ bụ 0.5° kwa nkeji. Aka nkeji ^[1]-na-atụgharị site na 360° na nkeji 60 ma ọ bụ 6° kwa nkeji

${\displaystyle \theta _{\text{hr}}=0.5^{\circ }\times M_{\Sigma }=0.5^{\circ }\times (60\times H+M)}$

ebe:

• θ bụ akụkụ dị n'ogo nke aka a tụrụ n'akụkụ elekere site na 12
• H bụ oge.
• M bụ nkeji gafere awa.
• MΣ bụ ọnụọgụ nkeji kemgbe elekere iri na abụọ. M Σ = (60 × H + M) {\displaystyle M_{\Sigma }= (60\oge H+M) }

${\displaystyle M_{\Sigma }=(60\times H+M)}$

${\displaystyle \theta _{\text{min.}}=6^{\circ }\times M}$

ebe:

• θ bụ akụkụ dị n'ogo nke aka a tụrụ ya na elekere site na ọnọdụ elekere iri na abụọ.
• M bụ nkeji.

Oge bụ 5:24. Akụkụ na ogo nke aka awa bụ:

${\displaystyle \theta _{\text{hr}}=0.5^{\circ }\times (60\times 5+24)=162^{\circ }}$

Akụkụ na ogo nke aka nkeji bụ:

${\displaystyle \theta _{\text{min.}}=6^{\circ }\times 24=144^{\circ }}$

Enwere ike ịchọta akụkụ dị n'etiti aka site na iji usoro a:

${\displaystyle {\begin{aligned}\Delta \theta &=\vert \theta _{\text{hr}}-\theta _{\text{min.}}\vert \\&=\vert 0.5^{\circ }\times (60\times H+M)-6^{\circ }\times M\vert \\&=\vert 0.5^{\circ }\times (60\times H+M)-0.5^{\circ }\times 12\times M\vert \\&=\vert 0.5^{\circ }\times (60\times H-11\times M)\vert \\\end{aligned}}}$

ebe

• H bụ oge
• M bụ nkeji

Ọ bụrụ na oghere ahụ karịrị ogo 180 wee wepụ ya na ogo 360.

Oge bụ 2:20.

${\displaystyle {\begin{aligned}\Delta \theta &=\vert 0.5^{\circ }\times (60\times 2-11\times 20)\vert \\&=\vert 0.5^{\circ }\times (120-220)\vert \\&=50^{\circ }\end{aligned}}}$

Oge ahụ bụ 10:16.

${\displaystyle {\begin{aligned}\Delta \theta &=\vert 0.5^{\circ }\times (60\times 10-11\times 16)\vert \\&=\vert 0.5^{\circ }\times (600-176)\vert \\&=212^{\circ }\ \ (>180^{\circ })\\&=360^{\circ }-212^{\circ }\\&=148^{\circ }\end{aligned}}}$

A na-etinye aka awa na nkeji naanị mgbe akụkụ ha bụ otu.

${\displaystyle {\begin{aligned}\theta _{\text{min}}&=\theta _{\text{hr}}\\\Rightarrow 6^{\circ }\times M&=0.5^{\circ }\times (60\times H+M)\\\Rightarrow 12\times M&=60\times H+M\\\Rightarrow 11\times M&=60\times H\\\Rightarrow M&={\frac {60}{11}}\times H\\\Rightarrow M&=5.{\overline {45}}\times H\end{aligned}}}$

Templeeti:Mvar is an integer in the range 0–11. This gives times of: 0:00, 1:05.Templeeti:Overline, 2:10.Templeeti:Overline, 3:16.Templeeti:Overline, 4:21.Templeeti:Overline, 5:27.Templeeti:Overline. 6:32.Templeeti:Overline, 7:38.Templeeti:Overline, 8:43.Templeeti:Overline, 9:49.Templeeti:Overline, 10:54.Templeeti:Overline, and 12:00. (0.Templeeti:Overline minutes are exactly 27.Templeeti:Overline seconds.)
