Speed Time Distance Calculator
Understanding the relationship between speed, time, and distance is essential in everyday life. Whether you’re planning a road trip, tracking your running pace, solving physics problems, or calculating travel time for work, the right formula makes everything easier.
Our Speed Time Distance Calculator is a fast, accurate, and user-friendly tool that helps you calculate:
- Distance (when speed and time are known)
- Speed (when distance and time are known)
- Time (when distance and speed are known)
It also supports multiple unit conversions including:
- mph (miles per hour)
- km/h (kilometers per hour)
- m/s (meters per second)
- Miles, kilometers, meters, and feet
- Hours, minutes, and seconds
This makes it perfect for students, drivers, athletes, engineers, and travelers.
The Basic Formula: Speed, Time & Distance
The calculator is based on three simple formulas:
1️⃣ Distance Formula
Distance = Speed × Time
2️⃣ Speed Formula
Speed = Distance ÷ Time
3️⃣ Time Formula
Time = Distance ÷ Speed
These formulas are fundamental in mathematics and physics and apply to real-world scenarios like driving, cycling, flying, running, and shipping.

Example Calculations
Example 1: Calculating Distance
- Speed: 60 mph
- Time: 2 hours
Distance = 60 × 2
Distance = 120 miles
Example 2: Calculating Speed
- Distance: 150 km
- Time: 3 hours
Speed = 150 ÷ 3
Speed = 50 km/h
Example 3: Calculating Time
- Distance: 300 miles
- Speed: 75 mph
Time = 300 ÷ 75
Time = 4 hours
Why Unit Conversion Matters
One of the biggest challenges when solving speed-time-distance problems is unit consistency.
For example:
- Speed in km/h
- Distance in miles
- Time in minutes
If units don’t match, calculations become incorrect.
Our calculator automatically converts everything internally before calculating. This ensures:
- Accurate results
- No manual conversions
- No calculation errors
