Converting Between Grams and Kilograms is a Grade 4 mathematics worksheet that builds fluency with metric mass conversions and calculations. Students complete 10 questions: 8 multiple-choice items and 2 fill-in-the-blank items. The worksheet asks them to convert mixed measurements such as kilograms and grams into grams, express grams as kilograms and grams, subtract masses, and add two package weights. The varied problems help students apply the relationship between kilograms and grams, including place-value situations with zero grams and calculations that require regrouping. Fill-in-the-blank questions require students to produce an answer rather than select one, while the multiple-choice items provide opportunities to identify and correct common conversion errors. This free printable worksheet is designed for Grade 4 math instruction, independent practice, review, or formative assessment, and it includes a complete answer key for efficient checking.

This Grade 4 worksheet practices converting mixed kilogram-and-gram measurements into grams, converting grams into kilograms and grams, and solving mass addition and subtraction problems. Its 10 items include 8 multiple-choice questions and 2 fill-in-the-blank questions, so students apply the 1-kilogram-to-1,000-gram relationship in both selected-response and written calculations.
First, review that 1 kilogram equals 1,000 grams and model a conversion such as 1 kg 500 g into 1,500 g. Then use the worksheet’s conversion items to have students explain how they handle values such as 25 kg 9 g, emphasizing the zero in the grams place. Finish with the subtraction and package-weight problems so students apply the same relationship when calculations involve mixed units.
Watch for students multiplying the kilogram amount by 100 instead of 1,000, dropping the zero in values such as 25 kg 9 g, or confusing 17 kg 84 g with 17,840 g instead of 17,084 g. In the calculation items, students may subtract or add the kilogram and gram numbers separately without regrouping, producing errors such as treating 1 kg − 237 g as 1,237 g. Have students label the unit of every intermediate answer.
You can assign this worksheet as a printable PDF or as a digital quiz on Wayground. It includes a complete answer key, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable format also supports schools that want to reduce screen time while students practice mass conversions.
Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font so the conversion choices, units, and fill-in-the-blank calculations are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when that supports access to the mixed-unit mass problems. These options change the worksheet file while keeping its kilogram-and-gram practice intact.
