mega.
The micro- (µ) prefix means one millionth (1/1000000) → 1 µm = 1/1000000 m → 1 m = 1000000 µm The centi- (c) prefix means one hundredth (1/100) → 1 cm = 1/100 m → 1 cm = 1/100 × 1,000,000 µm = 10,000 µm → 1 µm = 1/10000 cm → 562 µm = 562 × 1/10000 cm = 0.0562 cm
500000+500000=1000000 400000+600000=1000000 700000+300000=1000000 200000+800000=1000000 900000+100000=1000000
If you count from 1 to 1000000 you count 1000000 numbers so there are 1000000 numbers in 1000000
1000000
1000000 dived by 100 is 10000 100 dived by 1000000 is 0.0001 In other words : 100/1000000 = 0.0001 1000000/100 = 10000
The prefix giga means a billion (a thousand millions).
kilo- prefix (k) means x 1000 milli- prefix (m) means x 0.0001 ⇒ kilo- = milli- x 1000000 ⇒ 99 kg = 99 x 1000000 mg = 99000000 mg = 9.9 x 107 mg
1x10^9 = Giga http://en.wikipedia.org/wiki/SI_prefix
The missing number is 1000000 (a million).
The mega- prefix means million ⇒ 3Mm = 3 x 1000000 m = 3000000 m
Mega is the prefix for 106 1000000 Kilo is the prefix for 103 1000 So Mega anything is 103 or 1000 times larger than the kilo of that thing
Micron is a more common term for a micrometre. The prefix micro means 1/1000000 and milli means 1/1000. So 1000000/1000 gives you 1000microns in a millimetre.
I guess you mean micrometers (μm): 10,000 µm = 1 cm. The micro- prefix means one millionth (1/1000000 or 0.000001) The centi- prefix means one hundredth (1/100 or 0.01) → 1 cm ÷ 1 µm = 1/100 m ÷ 1/1000000 m = 1/100 m × 1000000/1 m = 1000000/100 = 1000000 ÷ 100 = 10000
1000000 1000000 1000000 1000000 1000000 1000000
1000000
1000000 - 1000000 = 0
The micro- (µ) prefix means one millionth (1/1000000) → 1 µm = 1/1000000 m → 1 m = 1000000 µm The centi- (c) prefix means one hundredth (1/100) → 1 cm = 1/100 m → 1 cm = 1/100 × 1,000,000 µm = 10,000 µm → 1 µm = 1/10000 cm → 562 µm = 562 × 1/10000 cm = 0.0562 cm
