# How to convert from base 4 to base 16?

I have the number 10011100010101 from base 4 and I need to conv in base 16. I wrote the number in pairs of 2 and tried to write it as such 0×16^0+1×16^1.. from left to right is it correct this way?

• What kind of a mutated oddity is a base $4$ number with nothing but zeroes and ones? Seems like it really wants to be binary. – John Jan 26 '18 at 17:18
• It's a 4 in this book... – Lola Jan 26 '18 at 17:20

$16 = 4^2$, so try splitting the number into blocks of two and convert those blocks separately
