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
200fL = _______pL
0.2pL
10^-15 - 10^-12
= 10^-3
Move the decimal 3 times to the left
0.0004dL = _______uL
40uL
10^-1 - 10^-6
= 10^5
Move the decimal 5 times to the right
2.5 mmol = ________ pmol
2,500,000,000 pmol
10^-3 - 10^-12
= 10^9
Move the decimal 9 times to the right
2.3 x 10^13 pm = __________m
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
42 x 10^12 cm = __________nm
42 x 10^19 nm
Since:
10^-2 - 10^-9 = 10^7
(10^12) + (10^7)
= 42 x 10^19 nm
