🔁 秒换算成毫秒（及微秒、纳秒）Seconds to Milliseconds (and Microseconds, Nanoseconds)

使用说明与常见问题How-to & FAQ

「秒换算成毫秒（及微秒、纳秒）」是什么？What is the Seconds to Milliseconds (and Microseconds, Nanoseconds) tool?

秒 × 1000 = 毫秒，同时给出微秒、纳秒和 时:分:秒.毫秒 写法。可输入负数（表示时间偏移）。本地处理。Seconds × 1000 = milliseconds, plus microseconds, nanoseconds and the h:mm:ss.mmm form. Negative values (time offsets) are allowed. Processed locally.

如何使用「秒换算成毫秒（及微秒、纳秒）」？How do I use the Seconds to Milliseconds (and Microseconds, Nanoseconds) tool?

在「秒换算成毫秒（及微秒、纳秒）」中，填写「秒」等参数，结果会随输入实时计算并显示在下方。In the Seconds to Milliseconds (and Microseconds, Nanoseconds): Fill in "Seconds"; results are recalculated instantly as you type.

为什么 0.1 秒显示为 100 而不是 100.00000000000001？Why does 0.1 s show 100 and not 100.00000000000001?

本页把结果按 13 位有效数字整理，消除二进制小数误差，所以 0.1 × 1000 显示为 100。Results are tidied to 13 significant digits, removing binary floating-point noise, so 0.1 × 1000 shows as 100.

能举个计算实例吗？Can you show a worked example?

例如在「秒换算成毫秒（及微秒、纳秒）」中填 秒 = 1.5，结果区显示：毫秒：1,500；微秒：1,500,000；纳秒：1,500,000,000；时:分:秒.毫秒：0:00:01.500For example, entering Seconds = 1.5 in the Seconds to Milliseconds (and Microseconds, Nanoseconds) gives: Milliseconds: 1,500; Microseconds: 1,500,000; Nanoseconds: 1,500,000,000; h:mm:ss.mmm: 0:00:01.500

哪些输入会被检查？Which inputs are validated?

「秒换算成毫秒（及微秒、纳秒）」会检查这些输入——「秒」：须为数字；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Seconds to Milliseconds (and Microseconds, Nanoseconds) checks its inputs — "Seconds": must be a number; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.

有哪些选项可以调整？What options can I adjust?

「秒换算成毫秒（及微秒、纳秒）」的设置：「秒」默认 1.5。每次生成结果都按当前设置处理。Settings in the Seconds to Milliseconds (and Microseconds, Nanoseconds) — "Seconds" default 1.5. The result always uses the current settings.

可以反向换算吗？Can I convert the other way?
