Time Unit worksheet

1. In milliseconds: 328,718,250,000 ms

1. First change to seconds, the shared unit: 1 average month = 2,629,746 s, so multiply

   $125\text{\hspace{0.17em}mo}\times \mathrm{2,629,746}$$=\mathrm{328,718,250}\text{\hspace{0.17em}s}$

2. Then change to milliseconds: 1 millisecond = 0.001 s, so divide by that

   $\frac{\mathrm{328,718,250}\text{\hspace{0.17em}s}}{0.001}$$=\mathrm{328,718,250,000}\text{\hspace{0.17em}ms}$
