Unit Conversion
36 cards
Card 1
Question: What does 'conversion' mean in measurements?
Answer: Changing from one unit to another or moving between subunits within the same unit (e.g., millimetres to centimetres).
Card 2
Question: What are the two types of conversion problems you might see on an exam?
Answer: 1) Conversions given in the question (e.g., 1 tsp = 4 g). 2) Conversions not given that you are expected to know (e.g., mm ↔ cm, L ↔ mL).
Card 3
Question: When a conversion is given, what is the recommended step to start solving conversion questions?
Answer: Always start by writing the given conversion first, then place the value from the question under the matching unit in that conversion.
Card 4
Question: What is the 'ALVN' method rule for given conversions?
Answer: Work anticlockwise: divide first, then multiply. Start with the value on the furthest right when forming the calculation.
Card 5
Question: Using the ALVN method, how do you calculate grams from teaspoons if 3 tsp = 12 g and the question asks for 8 tsp?
Answer: Place 8 under 3, then anticlockwise: 12 ÷ 3 × 8 = 32 g.
Card 6
Question: Using the ALVN method, how do you calculate teaspoons from grams if 3 tsp = 12 g and the question gives 15 g?
Answer: Place 15 under 12, then anticlockwise: 15 ÷ 12 × 3 = 3.75 tsp.
Card 7
Question: How do you apply the ALVN method to convert 15 in to metres given 2 in = 0.0508 m?
Answer: Write 2 in = 0.0508 m, place 15 under 2, then anticlockwise: 0.0508 ÷ 2 × 15 = 0.381 m.
Card 8
Question: What must you always ensure when placing the given value under the conversion?
Answer: Place the value under the matching unit in the given conversion (same unit underneath same unit).
Card 9
Question: Which common unit relationships (length, weight, capacity) are you expected to know for conversions not given in the exam?
Answer: Examples include mm ↔ cm, cm ↔ m, m ↔ km, L ↔ mL, and similar within weight and capacity (moving between subunits).
Card 10
Question: How many millimetres are in a centimetre, centimetres in a metre, and metres in a kilometre?
Answer: 10 mm = 1 cm; 100 cm = 1 m; 1,000 m = 1 km.
