Servo Torque & Speed Converter
Convert servo torque between kg·cm, oz·in, lb·in, and N·m, and turn a sec/60° speed spec into an actual transit time for your steering's real throw angle.

Speed & transit time
Most steering setups don't use the full 60° the spec is measured over — enter your actual lock-to-lock throw (check your servo horn and linkage geometry, or just measure it) to see the real time your steering takes to move end to end, not just the raw spec number.
A note on voltage
Torque and speed specs both change with input voltage — most servo listings show two or three figures (e.g. 4.8V / 6.0V / 7.4V), with higher voltage giving more torque and faster transit time. That relationship isn't linear or consistent enough across servos to convert reliably with a formula, so use the spec listed at the voltage you'll actually run (check your receiver/BEC output), not a different one.
How this works
Servo torque is a measure of rotational force — how much resistance the servo can push against before it stalls. Different brands and regions label it differently (kg·cm is most common on spec sheets, oz·in shows up a lot in US listings, and lb·in or N·m occasionally too), so converting them to a common unit is the only way to actually compare two servos from different listings.
Speed is listed as time per 60° of rotation, which is a fixed test angle used across the industry — it's not how far your steering linkage actually moves. Converting it to your real throw angle gives you the number that actually matters: how fast your wheels go from full lock one way to full lock the other.
