mass = kilogram
distance = meter time = second temperature = kelvin amount of material = mol electrical current - ampere luminous intensity = candela |
|
|
What is the equation for velocity?
In which 2 ways can it be manipulated? |
Distance / Time
D = VT T = D / V |
|
|
What is the equation for density?
In which 2 ways can it be manipulated? |
Mass / Volume
M = DV V = M / D |

Metric System
|
Units of appropriate increments by combining prefixes with roots
|
|
|
How to convert between metric units
|
If going from large to small unit, exponent is positive
If going from small to large unit, exponent is negative |
|
|
Metric system roots
|
distance = meter
mass = gram volume = liter energy = Joule |
|
|
1 mL = ?
1 L = ? |
1 mL = cm^3
1 L = dm^3 |
|
|
Conversion schemes: English to Metric
Distance 1 in = cm Mass 1 lb = g Volume 1 L = qt |
1 in = 2.54 cm
1 lb = 453.6 g 1 L = 1.057 qt. |
|
|
Conversion schemes
1 yd = ft 1 gal = qt 1 qt. = oz. 1 hr = sec |
1 yd = 3 ft
1 gal = 4 qt 1 qt. = 32 oz. 1 hr = 3600 sec |

When doing dimensional analysis, always look out for...!!!!!
|
a unit raised to an exponent (squared, cubed)
Will need to raise equivalency to this exponent!! |

Equation for °C to °F
|
°F = (1.8) °C + 32°F
|
|
|
Equation for °F to °C
|
°C = (°F - 32°F) / 1.8
|
|
|
Equation for °C to °K
Equation for °K to °C |
K = °C + 273.15
°C = K - 273.15 |
