Do a simple unit conversion. There are 10^9 m in 1 Gm.

first you have to know what a Gm is.
this is sort of how it goes:
1 Gm = 1 x 10^(9) m
1 Mm = 1 x 10^(6) m
1 km = 1 x 10^(3) m
1 m
1 cm = 1 x 10^(-2) m
1 mm = 1 x 10^(-3) m
1 um = 1 x 10^(-6) m
Now, you set them up to cancel units... or just call it converting
0.3 Gm/s * (1 x 10^(9) m / 1 Gm)
that should give you
3 x 10 ^ 8 m/s (standard, by the book, speed of light in a vacuum)

In metric units, the spped of light, c, is exactly 299,792,458 metres per second (1,079,252,848.8 km/h) but is commonly used in rough estimates. Note that this speed is a definition, not a measurement. Since the fundamental SI unit of length, the metre, has been defined since October 21, 1983 in terms of the speed of light, one metre is the distance light travels in a vacuum in 1/299,792,458 of a second. Thus, any further increase in the precision of the measurement of the speed of light will actually change the length of the metre; the speed of light will remain precisely 299,792,458 m/s. In imperial units, the speed of light is about 186,282.397 miles per second, that is about one foot per nanosecond.
