| definition = The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the [[Planck constant]] {{mvar|h}} to be {{val|6.62607015|e=-34}} when expressed in the unit J⋅s, which is equal to kg⋅m<sup>2</sup>⋅s<sup>−1</sup>, where the metre and the second are defined in terms of [[Speed of light|{{mvar|c}}]] and [[Caesium standard|{{math|Δ''ν''<sub>Cs</sub>}}]].

'''কিলোগ্ৰাম''' চমূকৈ '''কেজি''' হৈছে '''ভৰৰ একক'''। ধ্ৰুপদী (অনা-আপেক্ষিকতাবাদী) [[পদার্থ বিজ্ঞান]]ত বস্তুত থকা পদার্থৰ পৰিমাণকে বস্তুটোৰ [[ভৰ]] বুলি কোৱা হয় আৰু ই বস্তুটোৰ অৱক্ষয় নোহোৱালৈকে সলনি হ'ব নোৱাৰে। আপেক্ষিকতাবাদী পদার্থ বিজ্ঞানত অৱশ্যে গতিশীল অৱস্থাত বস্তুৰ ভৰ [[দ্ৰুতি|বেগ]] বঢ়াৰ লগে লগে বাঢ়ি যায় বুলি ধৰা হয়। যিহেতো পোহৰৰ [[দ্ৰুতি|বেগ]]তকৈ কোনো বস্তুৱেই বেছি বেগত যাব নোৱাৰে গতিকে পোহৰৰ বেগত গতি কৰা বস্তুটোৰ ওপৰত যিমানেই বল প্ৰয়োগ কৰা নহঁওক লাগিলে তথাপিতো তাৰ ত্বৰণ ঘটাব নোৱাৰি। নিউটনীয় বলৰ সংজ্ঞা অনুসৰি সেয়ে সেই অৱস্থাত বস্তুটোৰ ভৰ অসীম হ'ব লাগিব।
