🔍 Understanding the Units

What is a Dyne Minute?

A dyne is a unit of force in the centimeter-gram-second (CGS) system. It’s defined as the force required to accelerate a mass of one gram at a rate of one centimeter per second squared.

• 1 dyne = 10⁻⁵ newtons (N)

When multiplied by time (in minutes), “dyne minute” becomes a measure of impulse or torque over time, although it’s quite rare and non-standard.

• 1 dyne-minute = 60 dynes·seconds = 60 × 10⁻⁵ N·s = 6 × 10⁻⁴ N·s

What is Pound-Foot per Hour?

Pound-foot per hour (lb·ft/hr) is a unit used to measure torque delivery over time in imperial systems. While less common than units like foot-pounds (ft·lb), this is sometimes used to describe mechanical work rates in engines or rotational systems.

To connect these two units, we need a bridge: impulse (force × time) in Newton-seconds to pound-foot per hour.

📐 Conversion Process: Step-by-Step

Let’s walk through how to convert 2.87 dyne minutes into pound-foot per hour.

Step 1: Convert Dyne Minute to Newton-Second

As shown above:

• 1 dyne = 10⁻⁵ N
• 1 dyne minute = 60 × 10⁻⁵ N·s = 6 × 10⁻⁴ N·s

So,

2.87 dyne minutes = 2.87 × 6 × 10⁻⁴ N·s
= 0.001722 N·s

Step 2: Convert Newton-Second to Pound-Foot per Second

Now we’ll convert from N·s to lb·ft/s.
To do that, we need the conversion factor:

• 1 N = 0.224809 lb
• 1 meter = 3.28084 feet

So, 1 N·m = 0.73756 lb·ft

But since N·s is impulse and not torque, we use:

1 N·s = 0.73756 lb·ft/s (approximately, under rotational systems)

Therefore:

0.001722 N·s × 0.73756 = 0.0012709 lb·ft/s

Step 3: Convert Seconds to Hours

To get lb·ft/hr, multiply by the number of seconds in an hour (3600):

0.0012709 lb·ft/s × 3600 s = 4.5753 lb·ft/hr

✅ Final Answer: 2.87 Dyne Minutes = 4.5753 Pound-Foot per Hour

So, the exact answer is:

⭐ 2.87 Dyne Minutes = 4.5753 Pound-Foot per Hour (lb·ft/hr)
