No problem.

Who could refuse somebody who signs his full name like that?

In one nanosecond:

(0.000 000 001 sec)(299 792 458 m/sec)

= 0.299 792 458 meters

Since you don't like that, then let's get it in centimeters,

= (0.299 792 458 m)(100cm /1m)

= 29.979 245 8 cm.

If you like bigger number, let's see it in millimeters,

= (29.979 245 8 cm.)(10mm /1cm)

= 299.792 458 mm.

In 1000 years:

We will use only 365 and 1/4 days for 1 year.

(1000yr)(365.25day /1yr)(24hr /1day)(3600sec /1hr)

= (3.15576 x 10^10) seconds, my calculator says.

= 31,557,600,000 sec.

= 31 trillion something seconds.

So,

(3.15576 x 10^10 sec)(299,792,458 m/sec)

= 9.460 730 473 x 10^18 m, my calculator says again.

= 9,460 730 473 000 000 000 meters.

= 9 460 730 473 000 000 kilometers.

In 13.7 Billion years

You're kidding.

The zeros will need very large monitor to show them.

Above we saw 3.15576 x 10^10 seconds in 1000 years.

That is 3.15576 x 10^7 seconds per year.

So in 13.7 billion years,

(1.37 x 10^7 yr)(3.15576 x 10^7 sec/1yr)

= (4.323 3912 x 10 ^14) seconds.

So,

(4.323 3912 x 10^14 sec)(2.997 924 58 x 10^8 m/1sec)

= 12.961 200 75 x 10^22 meters

= 12.961 200 75 x 10^19 kilometers

That means

about 13, followed by 22 zeros, meters.

about 13, followed by 19 zeros, kilometers.
