Understanding Speed Units

Speed measures the distance traveled over time. Different regions and industries use different units of speed. In metric systems, meters per minute (m/min) and kilometers per hour (km/h) are common. In imperial systems, inches per minute (in/min), feet per minute (ft/min), and miles per hour (mph) are used.

Common Speed Conversions

• 1 meter per minute (m/min) ≈ 39.3701 inches per minute (in/min)
• 1 foot per minute (ft/min) = 12 inches per minute (in/min)
• 1 mile per hour (mph) ≈ 1.60934 kilometers per hour (km/h)
• 1 knot = 1.852 kilometers per hour (km/h)

Fun Fact: Nautical Miles and Knots
