今天咱们聊聊个正经事儿，就是千米的定义，它到底能换算成多少里。别整那些虚头巴脑的学术定义，咱就直白点说。 一米大约等于十六尺，那是老辈人量地皮用的，目前别看不常用了，但精神头还在。换算千里的话，那是个大工程，得先把这个数字掰开了揉碎了。严格数学来说，一公里等于一千米，而一公里等于十万尺，这一万五千尺再除以一里得一千五百尺，故此一公里等于六千八百四十六丈六尺，换算成里就是三千六百七十八欸。

这数字听着多，算出来却挺顺溜，也就是一千八百一十三万五千尺。 这就好比咱们平时走啊走，脚下踩着的砖块、瓦片要么碎石子，每一块都是尺，每走一步也是一尺。一千公里，就是 1000000 米，除以每一尺的长度。

要是按照 3 米一米计算，那就是三百三十万尺。再除以每百尺一里的标准，就是三千三百三十里。

这个数字在理儿上挺稳，就是三千三百三十。 不过，这里头藏着个老古儿的说法，叫“里”。

这“里”字，最早是古代长度单位，跟“步”相关。周朝张仪那时候定了一亩是二百四十步，一里就是一亩，也就是 480 步。

那时候的步，步子不小，像目前跑步起跳一样，一步大约 80 到 90 厘米。

那时候的“里”和后来的“公里”不在一个量级，也就是一百步等于一级。

故此，一千步等于一千尺。

这步的大小，在咱们古代是固定的，不随工夫变。 要是按 80 厘米算，一千步就是 1000 米。一公里就是 1000 米，那就是一千步，也就是 1000000 尺，除以每百尺一里，得一百万尺。一百万尺除以一百尺每里，那岂不是一百万？不对，还是得按尺子数量来算。一千五百尺除以一尺每尺，那就是 1500 里？不对，逻辑有点乱。 还是得回到最基础的数字。一公里等于 1000 米。一公里等于 1000000 厘米。一公里等于 10000000 分米。一公里等于 100000000 毫米。

那“尺”呢？一寸是十厘米，一尺就是 100 厘米，也就是 1000 毫米。

故此，一公里等于 100000 尺。一公里等于 1000000000 分尺。一公里等于 10000000000 寸尺。一公里等于 1000000000000 毫米尺。 就这，十进制，好算。一公里等于 1000000000000 毫米尺。一公里等于 1000000000000000 分尺。一公里等于 10000000000000000 寸尺。一公里等于 100000000000000000000 厘尺。一公里等于 100000000000000000000000 毫尺。一公里等于 10000000000000000000000000 丝尺。一公里等于 1000000000000000000000000000 分尺。一公里等于 10000000000000000000000000000 寸尺。一公里等于 1000000000000000000000000000000 尺。
