5 卷上:
商高曰:「平矩以正繩,偃矩以望高,覆矩以測深,臥矩以知遠,環矩以為圓,合矩以為方。方屬地,圓屬天,天圓地方。方數為典,以方出圓。笠以寫天。天青黑,地黃赤。天數之為笠也,青黑為表,丹黃為裏,以象天地之位。是故知地者智,知天者。智出於句,句出於矩。夫矩之於數,其裁制萬物,唯所為耳。」周公曰:「善哉!」

其次,日冬至所北照,過北衡十六萬七千里。為徑八十一萬里,周二百四十三萬里。分為三百六十五度四分度之一,度得六千六百五十二里二百九十三步、千四百六十一分步之三百二十七。過此而往者,未之或知。或知者,或疑其可知,或疑其難知。此言上不學而知之。故冬至日晷丈三尺五寸,夏至日晷尺六寸。冬至日晷長,夏至日晷短。日晷損益,寸差千里。故冬至、夏至之日,南北遊十一萬九千里,四極徑八十一萬里,周二百四十三萬里。分為度,度得六千六百五十二里二百九十三步、千四百六十一分步之三百二十七。此度之相去也。
