Metric to metric conversions

QUESTION : 2.65 kg = _______ g

ANSWER:

2.65 kg X 1000 g = 2650 g

1kg

Numerator (kg) and Denominator (kg) units cancel to leave grams (g)!

OR -- move decimal three places to the right

Metric to Metric Conversions

Try these use the ratio for dimensional analysis see slides 3 and 4

Ex. 167 cm = __________ m

  • 5347 L = __________ mL

  • 48 mg = __________ g

  • 0.645 cm = __________ mm

  • 789 mL = __________ L

  • 4370 g = __________ kg

  • 9677 mL = ___________ mL

TRY THESE! (USE THE RATIO FOR DIMENSIONAL ANALYSIS!!) SEE SLIDES # 3 AND 4)

Try these answers

167 cm X 1 m / 100 cm = 1.67m

  • 5347 L X 1000 mL/ 1L =5.347mL

  • 48 mg X 1 g/ 1000 mg = 0.048 g

  • 0.645 cm X 1 m / 100 cm X 1000 mm/ 1 m = 6.45 mm

  • 789 mL X 1 L / 1000 mL= 0.789 L

  • 4370 g X 1 kg / 1000 g = 4.370 kg

  • 9677 mL X 1 L / 1000000 mL X 1000 mL/ 1 L = 9.677 mL

TRY THESE! - ANSWERS!

Conversion calculations try these

  • 525 cm = __________ in

  • 645 mL = __________ tsp

  • 330 g = __________ lbs

  • 50 mi = __________ km

  • 56 gal X = __________ L

  • 345 oz = __________ g

Conversion Calculations – TRY THESE!!

Conversion calculations answers

  • 525 cm X 1 in / 2.54 cm = 206.7 in

  • 645 mL X 1tsp/ 5 mL = 129 tsp

  • 330 g X 1 kg/ 1000 g X 2.2lbs/ 1 kg = 0.15 lbs

  • 50 mi X 0.6 km / mi = 30 km

  • 56 gal x 3.785 L / gal = 212 L

  • 345 ozX 28.4 g / oz = 9798 g
