Metric Conversions?

Question

2000 mg = ______ ng
5 nl = _______ mL
104 km = _______ hm
50 cm = ______ hm
5.6 m = ______ nm

Answer 1

2000 mg = 2000 * 1000000 ng
5nL = 5/1000000 mL
104 km = 1040 hm
50 cm = 50/1000 hm
5.6 cm = 5.6*1000000000 nm

Some Metric conversions( I have mentioned only the prefixes )

1 yotta = 1000 zeta
1 zeta= 1000 exa
1 exa=1000 peta
1 peta= 1000 tera
1 tera=1000 giga
1 giga= 1000 mega
1 mega=1000 kilo
1 kilo=10 hecto
1 hecto=10 deca
1 deca=10
1 = 10 deci
1 deci=10 centi
1 centi=10 milli
1 milli=1000 micro
1 micro=1000 nano
1 nano=1000 pico
1 pico=1000 femto
1 femto=1000 atto
1 atto=1000 zepto
1 zepto=1000 yocto
Add the required post-fix to the value.(like: 1 metre= 10 deci-metre)
YOU MAY NEED ONLY A FEW OF THESE NOW!!!! DONT REMEMBER ALL THESE!!!

Answer 2

2000 mg = 2*10^9 ng (two billion)
5 nl = 5*10^6 mL (five million)
104 km = 1040 hm
50 cm = 50*10^-4 hm
5.6 m = 5.6*10^9 nm
