القياسات المترية الأساسية

فيما يلي بعض القياسات المترية الأساسية:

الطول:*المتر (م)

الوزن:*الكيلوجرام (كجم)

الحجم:*اللتر (لتر)

التحويل بين القياسات المترية

يمكن تحويل القياسات المترية بسهولة إلى وحدات أخرى باستخدام عوامل التحويل التالية:

الطول:*1 متر = 100 سنتيمتر (سم) = 1000 ملليمتر (مم)

الوزن:*1 كيلوغرام = 1000 جرام (جم)

الحجم:*1 لتر = 1000 سم3 = 1000 مل

مثال:

لتحويل 10 سنتيمترات إلى أمتار ، نستخدم المعادلة التالية:

10 سم / 100 سم = 0.1 م


هذا يعني أن 10 سنتيمترات تساوي 0.1 متر.
