When the National Bureau of Standards designed  a glider that could carry a 1000-pound bomb, they just needed to invent a guidance system  to steer it and release the explosive.

当国家标准局设计出可以携带 1000 磅炸弹的滑翔机时，他们只需要发明一个制导系统来引导它并释放炸药。

And so Congress basically said to National Bureau of Standards at the time, we need you to come up with standard samples of steel so that everyone can be on the same page.

因此国会当时基本上对国家标准局说，我们需要你们拿出钢材标准样品， 以便每个人都能达成共识。

So, if you want to nerd out, there's a really detailed and surprisingly readable history of the US journey towards metric, written in 1971, from the National Bureau of Standards and the US Commerce Department.

因此，如果您想消磨时间，美国国家标准局和美国商务部于 1971 年撰写了一份非常详细且可读性极强的美国公制之旅历史。
