Human hair growth rates can vary widely among individuals, but the range you provided suggests a typical growth rate might fall between approximately 0.000685 cm per hour (or 0.0685 mm/hour) to 0.02329 cm per hour (or 2.329 mm/hour).
To put these figures into perspective:
-
Minimum Growth Rate:
- \(6.849 \times 10^{-4} , \text{cm/hour} = 0.000685 , \text{cm/hour} = 0.0685 , \text{mm/hour}\)
-
Maximum Growth Rate:
- \(2.329 \times 10^{-2} , \text{cm/hour} = 0.02329 , \text{cm/hour} = 2.329 , \text{mm/hour}\)
Annual Growth Calculation: If we want to calculate how much hair would grow in a year (assuming continuous growth):
-
Minimum Growth in a Year:
- \(0.000685 , \text{cm/hour} \times 24 , \text{hours/day} \times 365 , \text{days/year} \approx 6.004 , \text{cm/year}\)
-
Maximum Growth in a Year:
- \(0.02329 , \text{cm/hour} \times 24 \times 365 \approx 204.1 , \text{cm/year}\)
Thus, under the conditions you've provided, hair can grow anywhere from about 6.004 cm to about 204.1 cm per year, depending on the individual's hair growth rate within that range.
