1 km = 1,000m

1mm = 10 cm

1000 g = 1kg

1 L = 1000 ml

Therefore

64km=64,000 m

897mm = 89.7cm

373g= .373kg

0.25L= 250 ml

Here's some more clues.

centi- = hundredths

milli = thousandths

kilo=thousands

Now km (kilometres, kilometers) are thousands of metres/meters so to convert 64 kilometres into metres, just multiply by a thousand.

Millimetres are thousandths of a metre, centimetres are hundredths of a metre, to convert from mm to cm you need to divide by 1000 to get to metres, then multiply by 100 to get cm (or more simply just divide by 10, which is the same thing.)

Hope this helps.
