Q

NOTE:

If the unknown unit is SMALLER than the known unit

ex: 200mL = ______ uL
= (10^-3 [mL] > 10^-6 [uL])
- If doing the equation: -3 - (-6) = +3, POSITIVE number indicates moving decimal to the RIGHT OR MULTIPLY it by 10, 3 times
——————————————————
If the unknown unit is LARGER than the known unit

ex: 200fL = ______ pL
= (10^-15 [fL] > 10^-12 [pL])
- if doing the equation: -15 - (-12) = -3, NEGATIVE number indicates moving decimal to the LEFT OR DIVIDE it by 10, 3 times

Q

200fL = _______pL

A

0.2pL

10^-15 - 10^-12
= 10^-3

Q

2.5 mmol = ________ pmol

A

2,500,000,000 pmol

10^-3 - 10^-12
= 10^9

Q

2.3 x 10^13 pm = __________m

A

230

Pico = 10^-12
“m” = 10^0 = 0

10^13 - 10^12
= 10^1 or 10
= 10^1 + 0 = 10

Move the decimal place by 1 time to the right

Q

42 x 10^12 cm = __________nm

A

42 x 10^19 nm

Since:
10^-2 - 10^-9 = 10^7

(10^12) + (10^7)

= 42 x 10^19 nm

Q

4.2 x 10^-3 dm = __________mm

A

0.42

Since:
10^-1 - 10^-3 = 10^2

(10^-3) + (10^2) = 10^-1

Move decimal to the left 1 time

17
Q

5.3 x 10^-2 fm = __________dm

A

5.3 x 10^-16

Since:
10^-15 - 10^-1 = 10^-14

(10^-2) + (10^-14) = 10^-16

18
Q

43 x 10^3 nm = __________mm

A

43 x 10^-3 / 0.043

Since:
10^-9 - 10^-3 = 10^-6

(10^3) + (10^-6) = 10^-3
