How do you convert 28km to cm?

Question

(i need help with chemistry)

Answer 1

learn how to use dimensional analysis

thats how i solve these conversiosn withotu a calculator  

Answer 2

A kilometre is 1000 metres, and a centimetre is 1/100 of a metre, so multiply by 100,000.

Answer 3

1 km= 1000 m = 1000 * 100 cm = 100000 cm

28 km= 2800000 cm

Answer 4

add 5 zeros.

28 km = 2800000cm

37km = 3700000cm

48km = 4800000cm

then you can also divide by 100 (take away 2 zeros) to get the answer in meters. You can also  look at the website below. Its great for metric conversion.

Answer 5

1km=1000m

100cm=1m

28km(1000m/1km)(100cm/1m)=2,800,000cm=...

Answer 6

Because:  1km=1000m and 1m=100cm:

28km  x 1000m x 100cm

--------------------------------------...   =  2 800 000cm

   1   x       1km     x    1m

The units above and below, cancels out to give you an answer in cm

Answer 7

Not a chemistry question, just a conversion question

28 km * 1000 m / 1 km * 100 cm / 1 m

ans = 2,800,000 cm
