m,µ.......
Can someone help me with this. I was absent from my Physics class today, and I don't have the textbook. My friend just gave me the questions, and I have no idea what to do here.

Please at least explain to me how to do it? :)

1 000 000 µm = 1 m
so 50 µm = 0.00005 meters

If there is one thing you need to learn, it's metric prefixes. You will use them in a variety of ways the rest of your life, no matter what you do. At least the most common ones such as k,M,G and c,m,µ.

SI (metric) prefixes:

da (deca) = x10 (rarely used)
h (hecto) = x100 (rarely used)
k (kilo) = x1000 = e3
M (Mega) = x1000000 = e6
G (Giga) = x1000000000 = e9
T (Tera) = x1000000000000 = e12
P (Peta) = e15
E (Exa) = e18
Z (Zetta) = e21
Y (Yotta) = e24

d (deci) = /10 = e-1 (rarely used)
c (cent) = /100 = e-2 (rarely used except for cm)
m (milli) = /1000 = e-3
µ (micro) = /1000000 = e-6
n (nano) = /1000000000 = e-9
p (pico) = /1000000000000 = e-12
f (femto) = e-15
a (atto) = e-18
z (zepto) = e-21
y (yocto) = e-24
