Hei has the element shown for his science experiment. How many kilograms of the material does he have? \( (1,000 \) grams = 1 kilogram \( ) \)

If Hei has 2,500 grams of the material, you can easily convert this to kilograms by dividing the number of grams by 1,000. So, \( 2,500 \, \text{grams} \div 1,000 = 2.5 \, \text{kilograms} \). Voilà! Hei has 2.5 kilograms of the material for his science experiment. Always remember to keep track of your units! A common mistake in unit conversion is forgetting to convert grams to kilograms correctly, resulting in inaccurate measurements. It’s always a safety net to double-check your conversions before diving into your experiment!
