How many kilojoules is 10,000 steps?

For a 70 kg person, 10,000 steps burns approximately 1,170 kJ (280 kcal). For an 85 kg person, it's about 1,420 kJ (340 kcal). Your weight significantly affects the energy burned.

How many kJ is 8,000 steps?

For a 70 kg person, 8,000 steps burns approximately 936 kJ (224 kcal). The calculation scales linearly - 8,000 steps is 80% of the energy burned in 10,000 steps.

How accurate is the steps to kJ conversion?

This is an estimate based on average walking pace and stride length. Actual energy expenditure varies with walking speed, terrain, and individual gait. It provides a useful ballpark for daily energy tracking.

How This Is Calculated

kcal = steps × 0.04 × (weight_kg ÷ 70)

steps: = number of steps walked
0.04: = estimated kcal per step at 70 kg reference weight
weight_kg: = your body weight in kilograms
70: = reference body weight (kg) for normalisation

Based on the Compendium of Physical Activities. Assumes moderate walking pace (~5 km/h). Actual energy expenditure varies with speed, incline, and fitness.
