To convert Jeff's height from centimeters to feet, we can use the given conversion ratio:
1 foot = 30.48 centimeters.
To find out how many feet tall Jeff is, we can use the formula:
\[ \text{Height in feet} = \frac{\text{Height in centimeters}}{30.48} \]
Plugging in Jeff's height:
\[ \text{Height in feet} = \frac{183 \text{ cm}}{30.48 \text{ cm/foot}} \approx 6.0039 \text{ feet} \]
Now rounding to the nearest whole number:
Jeff is approximately 6 feet tall.
