    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.
