Sim Racing Load Cell Calculator

Translate real-world racing brake pressures (kg or lbs) into exact simulator pedal percentages. Perfectly replicate an F1 car, GT3, or street car on your rig.

Real-World Baselines

*Note: Sim pedals do not have hydraulic assist like street cars. A 35kg push on a load cell takes significantly more leg effort than pushing a street car pedal to the floor, as you are pushing against rigid elastomers instead of a booster.

Software Calibration

Set BRF / Max Force Slider To:

65%

Set your Fanatec Control Panel (BRF), Moza Pit House, or Simagic software Max Force slider to 65% to reach 100% in-game braking when you push exactly 65KG (143LBS).

Methodology

This calculator converts your desired physical brake force into a software "BRF / Max Force" percentage by dividing the target force by the load cell capacity: BRF% = (Target / Capacity) × 100. Inputs may be entered in kilograms or pounds; both units are shown.
