How many grams are needed for 3 batches?' - Compare 2.5 litres and 2,450 ml by converting to the same unit - Solve a multi-step problem involving time, distance, and unit conversion ## Lesson: Converting Between Units A kilogram and a gram both measure weight. A litre and a millilitre both measure liquid. To solve real problems, you often need to swap between the two units. Remember these two facts: 1 kilogram equals 1000 grams, and 1 litre equals 1000 millilitres. To change kilograms into grams, or litres into millilitres, multiply by 1000. That moves the decimal point three places to the right. **Example.** A recipe uses 0.6 kg of flour for one batch. First convert to grams: 0.6 kg × 1000 = 600 g. For 4 batches, multiply by 4: 600 g × 4 = 2400 g. *(drawing: 3.2 litres equals 3200 millilitres, which is more than 3150 millilitres.)* Before you compare or add measurements, put them in the same unit first. The number alone can trick you: 3150 looks bigger than 3.2, but once you convert, 3.2 litres turns out to be more. **Recap.** Multiply by 1000 to turn kilograms into grams or litres into millilitres, and always convert to the same unit before comparing or adding. ## Practice 16 questions on this page, each with its working shown. ## Needs first - [Converting units with decimal notation](https://lightmysky.com/learn/mathematics/converting-units-with-decimal-notation-mt_2VpdPjvewx) - [Measure word problems with fractions and decimals](https://lightmysky.com/learn/mathematics/measure-word-problems-with-fractions-and-decimals-mt_5HV4mbgSGH) ## Opens up - [Unit Conversions](https://lightmysky.com/learn/mathematics/unit-conversions-mt_tpT9brpI6D)
