Pro Tip

When converting between height units, remember that precision matters. A height of 5'9" is exactly 69 inches, which converts to 175.26 centimeters. For most practical purposes, rounding to 175.3 cm or 1.75 m is appropriate. However, for medical or scientific applications, maintain the full precision. Also, remember that height can vary slightly throughout the day due to spinal compression - you're typically tallest in the morning and shortest in the evening. For consistent measurements, always measure at the same time of day and under similar conditions.
