"I heard Anas bin Malik say: 'The Messenger of Allah ﷺ used to perform Wudu' with a Makkuk (cup) and Ghusl with five Makkuks (cups).'"  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ يَتَوَضَّأُ بِمَكُّوكٍ وَيَغْتَسِلُ بِخَمْسَةِ مَكَاكِيَّ  

It was narrated from 'Aishah that the Messenger of Allah ﷺ used to perform Ghusl with a Mudd and Ghusl with approximately a Sa'.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَتَوَضَّأُ بِمُدٍّ وَيَغْتَسِلُ بِنَحْوِ الصَّاعِ  

"The Messenger of Allah ﷺ used to perform Ghusl with a Mudd and Ghusl with a Sa'."  

كَانَ رَسُولُ اللَّهِ ﷺ يَتَوَضَّأُ بِالْمُدِّ وَيَغْتَسِلُ بِالصَّاعِ
