4 of them.
there are 2 significant figures
All of those figures are significant. If you want to round it to 2 sig figs, that would be 13.
There are two significant figures: 2 and 0 The significant figures of a number are those digits that carry meaning contributing to its precision. Leading zeros (the zero before the 2) are not significant.
Rounded to three significant figures, one millimetre is equal to 0.000000621 miles.
You can convert distance from miles to kilometers by just multiplying the number of miles with 1.6 . Likewise you can convert kilometers to miles by just multiplying the number of kilometers by 0.62 . So, in this case the answer is 18.64 miles.

The distance measurement of 20.070 km has five significant figures. This includes the digits 2, 0, 0, 7, and the final 0, which is significant because it is to the right of the decimal point. Leading zeros are not significant, but trailing zeros in a decimal measurement are considered significant.
3.774 is to 4 significant figures (count them)
1,000 m = 1 km If there is not decimal point at the end of 1000. it is just 1km. If there is a decimal point the correct significant figures would be 1.000 km
Assuming the final zero is not there for decorative purposes, 6 sig figs.
Approx 3480 miles.
